Understanding the relationship between dog ownership and children's physical activity and sedentary behaviour

Combatting rabies outbreaks in Vietnam: High time to enforce restrictions on dog meat farming, a key source of transmission

In Vietnam, farming dogs for meat is not illegal but is increasingly marginalized as dog meat consumption comes under heightened social scrutiny. This loosely regulated practice likely increases the risk of rabies transmission to humans. At a time when human-wildlife conflict has become a major discussion point for global health, stray dogs escaping or being deliberately released from dog farms is a cause for serious concern. The first half of 2024 saw a significant spike in the incidence of human rabies cases, occurring in not just rural hot spots but also urban conurbations. Bites from rabid feral dogs are the primary source of infection, the distribution of which often clusters in the vicinity of battery farms or slaughterhouses that have recently downscaled or closed their business. Addressing this risk requires pursuing a One Health strategy that focuses on catching and euthanizing rabid dogs, vaccinating healthy dogs, implementing safety measures during dog slaughtering, and regulating dog meat trade. By robust enforcement of this comprehensive plan, it is hoped to prevent rabies outbreaks and protect public health. Hanoi is already taking the lead in introducing measures to avert a rabies crisis in the Vietnamese capital.

Effects of dog ownership on children's social-emotional development: findings from the PLAYCE cohort study

INTRODUCTION

Dog ownership is common in families with children and could play a role in children's social-emotional development. This study used longitudinal data on dog ownership and changing dog ownership to investigate their effects on young children's social-emotional development.

METHODS

Parents reported family dog ownership when their child was aged 2-5 years and at 5-7 years. Children (n = 591) were assigned to a dog ownership group by combining their current and prior dog ownership status. The parent-report Strengths and Difficulties Questionnaire (SDQ) measured children's social-emotional development at 5-7 years. Analyses included linear, Poisson, and logistic regression and adjusted for socio-demographic factors.

RESULTS

Girls who acquired a dog had significantly higher peer problems scores than non-dog owner girls (exp(β) = 1.8; 95% CI 1.3, 2.6). Boys who acquired a dog had significantly lower peer problems scores than continuing non-dog owner boys (exp(β) = 0.5; 95% CI 0.3, 0.8). There were no other significant effects observed between dog ownership group and SDQ scores or the odds of having abnormal scores.

CONCLUSIONS

Overall, changing or continuing dog ownership status had minimal impact on young children's social-emotional development. Future longitudinal research should examine the effects of dog ownership on child development by family characteristics and attachment to the dog.

IMPACT

Dog acquisition was associated with higher peer problems for girls and lower peer problems for boys, but not the odds of having abnormal peer problems scores. Dog acquisition, dog loss, and continuing dog ownership status were not associated with other measure of social-emotional development. This study used longitudinal data to examine effects of dog ownership on child development. Overall, changing or continuing dog ownership status had minimal impact on young children's social-emotional development. Since dog ownership is selected into, longitudinal research is needed to confirm if changes in children's social-emotional development occur following changes in dog ownership.

Australian children's physical activity and screen time while in grandparental care

OBJECTIVE

The objective of this study was to explore Australian children's engagement in physical activity and screen time while being cared for by their grandparents.

METHOD

Grandparents (N = 1,190) providing ≥3 hours of weekly care to a grandchild aged 3-14 years completed an online survey assessing their grandchildren's movement behaviours while in their care. Descriptive statistics were computed for frequency of engagement in unstructured and structured physical activities, minutes spent playing outdoors, and minutes spent engaged in screen time. Regression analyses were conducted to assess socio-demographic predictors of movement behaviours.

RESULTS

Playing in the yard was the most common form of physical activity in which grandchildren reportedly participated (77% 'usually' or 'always'), followed by playing with toys/equipment (62%). Few (14-36%) frequently engaged in active transport. Children spent an average of 181 minutes per week engaged in screen-based activities.

CONCLUSIONS

There is an opportunity to improve children's movement behaviours while in grandparental care. Communicating to grandparents their importance in supporting an active lifestyle is warranted.

IMPLICATIONS FOR PUBLIC HEALTH

Findings highlight the importance of creating environments that facilitate play-based, outdoor activities. Ensuring children have access to play equipment while in the care of grandparents and improving access to and quality of neighbourhood parks may assist with activity promotion.

Pet ownership: A sign of superior socioeconomic position? Evidences from six cities in China

The aim of this study was to assess the prevalence of pet ownership and the relationship between pet ownership and people's socioeconomic positions examined at the individual, household, and regional levels among a large representative sample of residents in China. A cross-sectional study was conducted among six cities in China, incorporating a total of 5782 male residents along with their families in the analysis. The multilevel logistic regression models were employed to determine associations between socioeconomic deprivation and pet ownership prevalence. Pet-keeping is common in China as about 21.6% (95% C.I. 18.4%-24.0%) of households in China owned pets. Male participants aged over 55 years (OR: 0.78, 95%C.I.0.66-0.98) and those who are married (OR: 0.79, 95%C.I. 0.65-0.97) exhibit a reduced likelihood of pet ownership when contrasted with individuals younger than 25 years and those who have never married. Participants originating from medium or large urban centers demonstrate a significantly elevated likelihood of pet ownership, with an odds ratio of 1.98 (95%C.I. 1.71-2.30), when compared to their rural counterparts. Households residing in areas with medium population density have a 1.73 (95%C.I. 1.21-2.19) times higher likelihood to own a pet compared to those in regions of low population density. Elevated levels of socioeconomic deprivation, both at home and regionally, are associated with a substantially reduced probability of pet ownership. This study provides concrete evidence to the prevalence of pet ownership and its demographic distribution in China. These findings suggest that keeping pets might be more available to people with higher socioeconomic status.

Walking and Playing with the Dog to Improve the Physical Activity Level of Adolescents: A Scoping Review

BACKGROUND

In recent years, new technologies such as the introduction of the smartphone and the tablet in everyday life and habits have often made adolescents sedentary. It is becoming a serious problem in society. It is important to propose, as soon as possible, proper and feasible programs to modify this trend. A solution should be to increase physical activity, reducing sedentary behaviors. Adopting dogs and walking and playing with them could be a solution, and the population should be sensitized about this aspect. Consequently, the objective of this scoping revision of the literature is to analyze the association between physical activity in adolescents and the presence of a dog in the family.

METHODS

Three electronic databases were screened until 21 February 2024. The detected articles were screened against the eligibility criteria. The results were narratively discussed.

RESULTS

After the screening process, a total of four studies were included. The studies presented heterogeneity in the physical activity assessment. This made it hard to synthesize the results. Indicatively, there is a positive association between physical activity and dog ownership.

CONCLUSIONS

walking and playing with the dog increase the physical activity level of adolescents. Therefore, a sensibilization campaign should highlight the importance of having dogs in families, especially in adolescence. It is fundamental to daily walk and play with them.

Longitudinal effects of dog ownership, dog acquisition, and dog loss on children's movement behaviours: findings from the PLAYCE cohort study

INTRODUCTION

Regular physical activity is important for children's physical and mental health, yet many children do not achieve recommended amounts of physical activity. Dog ownership has been associated with increased physical activity in children, however, there have been no longitudinal studies examining this relationship. This study used data from the Play Spaces and Environments for Children's Physical Activity (PLAYCE) cohort study to examine the longitudinal effects of dog ownership status on children's movement behaviours.

METHODS

Change in dog ownership from preschool (wave 1, age 2-5) to fulltime school (wave 2, age 5-7) was used as a natural experiment with four distinct dog ownership groups: continuing non-dog owners (n = 307), continuing dog owners (n = 204), dog acquired (n = 58), and dog loss (n = 31; total n = 600). Daily movement behaviours, including physical activity, sedentary time, sleep, and screen time, were measured using accelerometry and parent-report surveys. Differences between groups over time and by sex were tested using linear mixed effects regression models.

RESULTS

Girls who acquired a dog increased their light intensity activities and games by 52.0 min/day (95%CI 7.9, 96.0) and girls who lost a dog decreased their light intensity activities and games by 62.1 min/day (95%CI -119.3, -4.9) compared to no change among non-dog owners. Girls and boys who acquired a dog increased their unstructured physical activity by 6.8 (95%CI 3.2, 10.3) and 7.1 (95%CI 3.9, 10.3) occasions/week, compared to no changes among non-dog owners. Girls and boys who lost a dog reduced their unstructured physical activity by 10.2 (95%CI -15.0, -5.3) and 7.7 (95%CI -12.0, -3.5) occasions/week. Girls who lost a dog decreased their total physical activity by 46.3 min/day (95%CI -107.5, 14.8) compared to no change among non-dog owners. Continuing dog ownership was typically not associated with movement behaviours. Dog ownership group was not associated with changes in sleep and had mixed associations with screen time.

CONCLUSION

The positive influence of dog ownership on children's physical activity begins in early childhood and differs by child sex. Further research should examine the specific contributions dog-facilitated physical activity makes to children's overall physical activity, including the intensity and duration of dog walking and play.

Impact of dog and/or cat ownership on functional constipation at 3 years of age: the Japan Environment and Children's study

PURPOSE

This investigation assessed the impact of dog and/or cat ownership during infancy on the presence of functional constipation (FC) at 3 years of age.

METHODS

The fixed data of 73,936 singleton births from a large national birth cohort study commencing in 2011 were used to identify FC as estimated by Rome III at 3 years of age. Multiple logistic regression analysis was employed to search for correlations between FC development and dog and/or cat ownership in early childhood.

RESULTS

A total of 8,459 toddlers (11.6%) met the Rome III criteria for FC at 3 years of age. Overall, 57,264 (77.5%) participants had never owned a dog or cat. We identified 7,715 (10.4%) infant-period owners, 1,295 (1.8%) current owners, and 7,762 (10.5%) long-term owners. Multivariate analysis showed that infant-period ownership remained significantly associated with the risk of developing FC at 3 years of age after adjusting for covariates (adjusted OR [95% CI] 1.09 [1.01-1.19] based on non-ownership).

CONCLUSIONS

This Japanese large nationwide survey uncovered a possible adverse effect of infant-period dog and/or cat ownership prior to 6 months of age on FC status at 3 years of age.

Exploring health behaviors and the role of pet dogs in households with autistic children: the DANE study

Introduction

Autism spectrum disorder (ASD) often presents a unique set of risk factors that impact healthy eating and physical activity. Animal-assisted interventions (AAI) are a promising approach for autistic children. There is growing evidence for the positive impact of AAIs on self-regulation, which is necessary for initiating and maintaining behavioral changes. Pet dogs offer several potential advantages as a vehicle for an AAI focused on health behaviors. However, little is known about the experiences of autistic children and their families with respect to dog ownership and the mechanisms through which such an AAI might operate.

Methods

We conducted interviews with ten parent-child dyads to explore the role of pet dogs in the lives and lifestyle habits of families with an autistic child. Interview guides were designed to explore the relationship between the autistic child and the pet dog and the role of the dog in family life; attitudes and practices related to physical activity and nutrition; and thoughts about intervention strategies. We used a directed qualitative content analysis approach for analysis.

Results

Themes indicate a strong bond between the child and the dog, the child's enjoyment in caring for their dog, and successful integration of dogs within family routines. In contrast, minor themes emerged around the challenges that owning a pet dog posed for families with an autistic child. In terms of nutrition and physical activity, a major theme among children was that healthy eating and exercise were important for both them and their dogs. However, minor themes suggest challenges with healthy eating and exercise and room for improvement for these behaviors. Parents held favorable views toward an intervention that would incorporate the family dog to teach children about nutrition and physical activity, although they expressed some concerns about feasibility.

Discussion

This exploratory work suggests that AAIs to improve nutrition and physical activity could build on the strong bond that children have with their pet dogs, but should consider the specific needs of each family, including the needs of the pet dog.

Are children and dogs best friends? A scoping review to explore the positive and negative effects of child-dog interactions

Personal wellbeing is greatly influenced by our childhood and adolescence, and the relationships formed during those phases of our development. The human-dog bond represents a significant relationship that started thousands of years ago. There is a higher prevalence of dog ownership around the world, especially in households including children. This has resulted in a growing number of researchers studying our interactions with dogs and an expanding evidence base from the exploration of child-dog interactions. We review the potential effects of child-dog interactions on the physical, mental, and social wellbeing of both species. A search of the SCOPUS database identified documents published between January 1980 and April 2022. Filtering for key inclusion criteria, duplicate removals, and inspecting the references of these documents for additional sources, we reviewed a total of 393 documents, 88% of which were scientific articles. We were able to define the numerous ways in which children and dogs interact, be it neutral (e.g., sharing a common area), positive (e.g., petting), or negative (e.g., biting). Then, we found evidence for an association between childhood interaction with dogs and an array of benefits such as increased physical activities, a reduction of stress, and the development of empathy. Nonetheless, several detrimental outcomes have also been identified for both humans and dogs. Children are the most at-risk population regarding dog bites and dog-borne zoonoses, which may lead to injuries/illness, a subsequent fear of dogs, or even death. Moreover, pet bereavement is generally inevitable when living with a canine companion and should not be trivialized. With a canine focus, children sometimes take part in caretaking behaviors toward them, such as feeding or going for walks. These represent opportunities for dogs to relieve themselves outside, but also to exercise and socialize. By contrast, a lack of physical activity can lead to the onset of obesity in both dogs and children. Dogs may present greater levels of stress when in the presence of children. Finally, the welfare of assistance, therapy, and free-roaming dogs who may interact with children remains underexplored. Overall, it appears that the benefits of child-dog interactions outweigh the risks for children but not for dogs; determination of the effects on both species, positive as well as negative, still requires further development. We call for longitudinal studies and cross-cultural research in the future to better understand the impact of child-dog interactions. Our review is important for people in and outside of the scientific community, to pediatricians, veterinarians, and current or future dog owners seeking to extend their knowledge, and to inform future research of scientists studying dogs and human-animal interactions.

Is Dog Owner Obesity a Risk Factor for Canine Obesity? A "One-Health" Study on Human-Animal Interaction in a Region with a High Prevalence of Obesity

Obesity in humans is a growing global problem and is one of the greatest public health challenges we face today. Most researchers agree that, as in humans, the incidence in the companion animal population is also increasing. The aim of this study was to evaluate the risk factors contributing to canine obesity in a region with a high rate of human obesity (Canary Islands, Spain), co-occurrence of obesogenic risk factors, and a canine population with a high percentage of unneutered dogs. We have focused on owner risk factors that promote obesity in humans, such as weight, lifestyle, nutritional habits, and low physical activity, among others. Thus, the human-animal interaction relationship that contributes to human obesity and influences canine obesity has been studied. A multicentre cross-sectional analytical study of 198 pairs of dogs from urban households and their owners was used. A multivariable logistic regression study was completed to analyse owner characteristics variables associated with canine obesity. This transdisciplinary study was conducted with physicians and veterinarians using a "One Health" approach. Our results suggest that, in a region of high obesogenic risk, obese/overweight dogs are primarily female, older than 6 years, and neutered. Being an overweight dog owner was found to be the most important factor in the occurrence of obesity in dogs. Owners of overweight dogs were mainly females, older than 40 years, who did not engage in any physical activity. A strong correlation has been found between dog owners with low levels of education and obesity in their dogs. We suggest that veterinarians should develop and design strategies to encourage pet owners to engage in physical activity with their dogs for the benefit of both.

A mobile health intervention to encourage physical activity in children: a randomised controlled trial

BACKGROUND

Despite immense benefits of physical activity on health and developmental outcomes, few children achieve recommended daily levels of physical activity. Given more than half of families with children own a dog, we investigated the effect of a mobile health (mHealth) intervention to encourage dog-facilitated physical activity through increased family dog walking and children's active play with their dog.

METHODS

The PLAYCE PAWS study was a three-armed randomised pilot trial conducted in Perth, Western Australia. Children aged 5-10 years with a family dog were randomised to 4 weeks of either 1) SMS-only intervention, 2) 'SMS + pedometer' intervention or 3) 'usual care' control. The mHealth intervention involved SMS messages to parents; the 'SMS + pedometer' group also received a dog pedometer and personalised dog steps diary. Parent-reported measures were collected at baseline, 1- and 3-months post intervention. The primary outcome was weekly frequency of family dog walking and dog play; secondary outcomes were child attachment to the dog and feasibility of the intervention.

RESULTS

A total of 150 children were randomised in staggered blocks to SMS-only (n = 50), 'SMS + pedometer' (n = 50) or usual care (n = 50). No differences were observed in family dog walking and dog play at 1-month. SMS-only children (OR 2.6, 95% CI 1.17, 5.83, P = 0.019) and all intervention children (OR 1.97, 95% CI 1.01, 3.86, P = 0.048) were more likely to increase total dog-facilitated physical activity (sum of family dog walking and dog play responses) at 3-months. The positive associations with total dog-facilitated physical activity disappeared (all P > 0.05) after adjusting for socio-demographic factors.

CONCLUSIONS

The PLAYCE PAWS mHealth intervention did not significantly affect dog-facilitated physical activity in children. Given high levels of dog ownership in the community, SMS prompts could be a low-cost intervention to encourage more physical activity in children. Further research is needed to understand how increased interaction with the family dog impacts on children's overall physical activity and other health and development outcomes.

Association between preschooler movement behaviours, family dog ownership, dog play and dog walking: Findings from the PLAYCE study

Physical inactivity in childhood is a major public health issue. Dog ownership has been widely reported to lead to greater physical activity in adults and school-aged children. We examined if dog ownership and dog-facilitated physical activity were associated with higher physical activity in preschoolers. Secondary analysis of the 'Play Spaces & Environments for Children's Physical Activity' (PLAYCE, 2015-2018) study involving 1366, 2-5-year-olds from 122 long day-care centres in Perth, Australia was conducted. Socio-demographics and movement behaviours (physical activity, screen time, sleep) were examined by dog ownership, dog play and dog walking. Dog-owning preschoolers did physical activity 8 times/week more but 6 min/day less park play than non-dog owners (all p < 0.05). Dog-owning preschoolers who played with their dog ≥ 3 times/week did more physical activity, outdoor play and had 16 min/day more sleep (all p < 0.05). For dog-owners, family dog walking ≥ 3 times/week was positively associated with preschooler physical activity, outdoor play and negatively associated with screen time (all p < 0.05). Our findings suggest that the physical activity-related benefits from having a family dog may be realised when preschoolers spend time playing and walking their dog. Dog walking and play, not dog ownership alone, may be an important source of physical activity for preschoolers.

Family Dog Ownership and Youth Physical Activity Levels: A Scoping Review

ABSTRACT

Higher youth physical activity (PA) is associated with favorable health outcomes. The PA Guidelines for Americans recommend school-aged children complete at least 60 minutes of daily PA. Only one in three children meet these guidelines. Dog walking and play are potential strategies to increase youth PA. This scoping review summarizes the existing literature on familial dog ownership and youth PA levels and identifies gaps in the literature to inform future studies. Of nine studies that compared PA levels among youth with and without dogs, 77.8% reported a positive association between dog ownership and PA. The majority of studies investigating dog ownership and youth PA are cross-sectional and suggest dog ownership is associated with increased youth PA. Longitudinal studies are needed to determine whether the relationship is causal. Interventions to increase dog-facilitated PA in youth also are needed. Future studies should examine the dog ownership-PA relationship in low-income and minority youth.

Backyard benefits? A cross-sectional study of yard size and greenness and children's physical activity and outdoor play

BACKGROUND

The home environment is the most important location in young children's lives, yet few studies have examined the relationship between the outdoor home environment and child physical activity levels, and even fewer have used objectively measured exposures and outcomes. This study examined relationships between objectively assessed home yard size and greenness, and child physical activity and outdoor play.

METHODS

Data were drawn from the HealthNuts study, a longitudinal study of 5276 children in Melbourne, Australia. We used cross-sectional data from a sample at Wave 3 (2013-2016) when participants were aged 6 years (n = 1648). A sub-sample of 391 children had valid accelerometer data collected from Tri-axial GENEActive accelerometers worn on their non-dominant wrist for 8 consecutive days. Yard area and greenness were calculated using geographic information systems. Objective outcome measures were minutes/day in sedentary, light, and moderate-vigorous physical activity (weekday and weekend separately). Parent-reported outcome measures were minutes/day playing outdoors (weekend and weekday combined). Multi-level regression models (adjusted for child's sex, mother's age at the birth of child, neighbourhood socioeconomic index, maternal education, and maternal ethnicity) estimated effects of yard size and greenness on physical activity.

RESULTS

Data were available on outdoor play for 1648 children and usable accelerometer data for 391. Associations between yard size/greenness and components of physical activity were minimal. For example, during weekdays, yard size was not associated with daily minutes in sedentary behaviour (β: 2.4, 95% CI: - 6.2, 11.0), light physical activity (β: 1.4, 95% CI: - 5.7, 8.5) or MVPA (β: -2.4, 95% CI: - 6.5, 1.7), with similar patterns at weekends. There was no relationship between median annual yard greenness and physical activity or play.

CONCLUSION

In our study of young children residing in higher socio-economic areas of Melbourne yard characteristics did not appear to have a major impact on children's physical activity. Larger studies with greater variation in yard characteristics and identification of activity location are needed to better understand the importance of home outdoor spaces and guide sustainable city planning.

Association between Early Life Child Development and Family Dog Ownership: A Prospective Birth Cohort Study of the Japan Environment and Children's Study

Pets may play a role in the social-emotional development of children. In particular, some studies have suggested that family dog ownership is associated with better health outcomes. To date, no study has assessed child development in association with dog ownership of different time points. The purpose of the current study was primary to investigate whether “ever” family dog ownership was associated with early child development, and secondary to further examine whether associations between family dog ownership and early child development differ among family dog ownership of status, including “past only”, “current only”, and “always” groups, using the data of family dog ownership obtained at multiple time points. Associations between family dog ownership and infant development at 3 years of age were examined using data from a nationwide prospective birth cohort study, the Japan Environment and Children’s Study (n = 78,941). “Ever” family dog ownership was categorized to “past only”, “current only”, and “always”. We observed that children with “ever” family dog ownership showed a significantly decreased risk of developmental delay in the communication (odds ratio [OR] = 0.87; 95% confidence interval [CI]: 0.78, 0.96), gross motor (OR = 0.83; 95% CI: 0.76, 0.92), problem-solving (OR = 0.89; 95% CI: 0.83, 0.96) and personal-social (OR = 0.86; 95% CI: 0.72, 0.92) domains compared to children with “never” family dog ownership. Furthermore, a significantly decreased risk of developmental delay in gross motor function was observed in association with living with dogs in the “past only” (OR = 0.83; 95% CI: 0.73, 0.95) and “always” (OR = 0.86; 95% CI: 0.75, 0.98). In addition, a decreased risk of developmental delay in the problem-solving domain was associated with “past” family dog ownership (OR = 0.87; 95% CI: 0.79, 0.97) and in the personal-social domain was associated with “always” family dog ownership (OR = 0.81; 95% CI = 0.68, 0.95). Given the possible positive association between early life child development and family dog ownership, living with dogs may be an important factor to be considered when assessing child development.

Barriers and motivators for preschoolers playing and walking with their dog: Results from qualitative research

ISSUES ADDRESSED

A large proportion of preschoolers do not meet the recommended three hours of daily physical activity. A potential source of daily physical activity could be that provided via the family dog. This qualitative study aimed to explore the barriers and motivators to preschoolers playing with their dog and participating in family dog walks.

METHODS

Twelve in-depth interviews were conducted with parents of preschoolers who owned a dog. A semistructured interview guide was used, and transcripts were analysed thematically.

RESULTS

Factors influencing preschoolers playing with their dog and participating in family dog walks included parents' level of attachment to their dog, parental history of dog ownership, parent modelling of safe dog play, type of play the family dog enjoys and proximity to dog- and child-friendly destinations. Other factors such as the size, level of socialisation and perceived exercise requirements of the dog, physical environment factors such as backyard size and individual factors such as time and existing commitments were also reported.

CONCLUSIONS

A number of dog, individual and physical environment specific factors should be considered when promoting preschooler physical activity through dog walking and play. SO WHAT?: A large proportion of preschoolers do not meet the recommended three hours of daily physical activity. In Australia, 43% of Australian households with children aged four to five own a dog. Dog-facilitated physical activity through family dog walks and active play could be an effective strategy for increasing preschooler physical activity.

The relationship between dog ownership, dog play, family dog walking, and pre-schooler social-emotional development: findings from the PLAYCE observational study

BACKGROUND

Regular physical activity provides children with health and developmental benefits. This study investigated if active play and walking with the family dog was associated with better social-emotional development in young children.

METHODS

We surveyed 1646 parents to ascertain if families with pre-schoolers owned a dog, and the frequency per week their child went on family dog walks or actively played with their dog. The parent-report version of the Strengths and Difficulties Questionnaire (SDQ) was used to measure children's social-emotional development.

RESULTS

Children from dog-owning households had reduced likelihood of conduct problems (odds ratio (OR) = 0.70; 95% confidence interval (CI): 0.54, 0.90), peer problems (OR = 0.60; 95% CI: 0.46, 0.79), and total difficulties (OR = 0.77; 95% CI: 0.59, 0.99) and increased likelihood of prosocial behavior (OR = 1.34; 95% CI: 1.06, 1.68) compared with children without a dog. Within dog-owning households, family dog walking at least once/week (OR = 1.45; 95% CI: 1.02, 2.08) and active play with the family dog three or more times/week (OR = 1.74; 95% CI: 1.16, 2.59) increased the likelihood of prosocial behaviors. Family dog walking at least once/week also reduced the likelihood of total difficulties (OR = 0.64; 95% CI: 0.42, 0.96).

CONCLUSIONS

Our findings highlight the possible physical activity and social-emotional developmental benefits of family dog ownership for pre-schoolers, and that these benefits may present in early childhood.

IMPACT

Young children from dog-owning families had lower peer problems and conduct problems, and higher prosocial behaviors than children from non-dog-owning families. Children of dog-owning families who walked or played with their dog more often also had better prosocial behaviors. Positive social-emotional development was associated with dog ownership, family dog walking, and dog play in young children. Highlights that the social-emotional benefits of owning a dog may begin early in childhood. Due to the high level of pet ownership in households with children, these findings suggest having a dog and interacting with it through play and walking may be important mechanisms for facilitating young children's social-emotional development.

A study protocol for a randomised controlled trial to evaluate the effectiveness of a dog-facilitated physical activity minimal intervention on young children's physical activity, health and development: the PLAYCE PAWS trial

BACKGROUND

Pet ownership brings many health benefits to individuals. In children developmental benefits can extend to improved self-esteem, better social competence and decreased loneliness. The majority of households with children own a dog, however only a small proportion of children gain the benefits of dog ownership through dog walking and play. There are few intervention studies investigating the impact of dog-facilitated physical activity in children. The PLAYCE PAWS study aims to test a minimal-contact intervention through the use of mobile health ("mhealth") strategies, i.e. text (SMS) messages, to parents to encourage their children to walk and play with their dog more, and evaluate the impact on children's overall physical activity and development.

METHODS/DESIGN

The PLAYCE PAWS intervention study will target parents in dog-owning families with children aged 5 to 8 years in Perth, Western Australia. Approximately 150 dog-owning parents and children will be randomly allocated into either one of two intervention groups or a 'usual care' control group. The first intervention group will receive SMS messages over 4 weeks to encourage and prompt parents to undertake dog walking and dog play with their child. The second intervention group will receive the same text messages, plus a dog pedometer and personalised 'dog steps' diary for their child to complete. Parent-reported outcome measures include changes in children's dog walking and play, overall physical activity, socio-emotional development, self-regulation, self-esteem, empathy, and level of attachment to their dog.

DISCUSSION

The PLAYCE PAWS study appears to be the first to examine the effectiveness of a low-cost, mhealth intervention for increasing young children's physical activity through dog walking and play. Given the high prevalence of dogs as family pets, this study presents a valuable opportunity to investigate if mHealth interventions encourage children to walk and play with their dog more, and if there are any associated impact on children's overall physical activity and socio-emotional well-being. If effective, a larger trial or program could be implemented at low-cost and with wide reach in the community.

Dog ownership and adults' objectively-assessed sedentary behaviour and physical activity

Evidence suggests a positive effect of dog ownership on physical activity. However, most previous studies used self-reported physical activity measures. Additionally, it is unknown whether owning a dog is associated with adults’ sedentary behaviour, an emerging health risk factor. In this study, physical activity and sedentary behaviour were objectively collected between 2013 and 2015 from 693 residents (aged 40–64 years) living in Japan using accelerometer devices. Multivariable linear regression models were used, adjusted for several covariates. The means of total sedentary time and the number of long (≥ 30 min) sedentary bouts were 26.29 min/day (95% CI − 47.85, − 4.72) and 0.41 times/day (95% CI − 0.72, − 0.10) lower for those who owned a dog compared to those not owning a dog, respectively. Compared with non-owners, dog-owners had significantly higher means of the number of sedentary breaks (95% CI 0.14, 1.22), and light-intensity physical activity (95% CI 1.31, 37.51). No significant differences in duration of long (≥ 30 min) sedentary bouts, moderate, vigorous, and moderate-to-vigorous-intensity physical activity were observed between dog-owners and non-owners. A novel finding of this study is that owning a dog was associated with several types of adults’ sedentary behaviours but not medium-to-high-intensity physical activities. These findings provide new insights for dog-based behavioural health interventions on the benefits of dog ownership for reducing sedentary behaviour.

"You can be blind because of loving them so much": the impact on owners in the United Kingdom of living with a dog with osteoarthritis

BACKGROUND

There is growing awareness that caring for a chronically ill pet may have a detrimental impact on their owner's quality of life. Companion animal orthopaedic disease has received little research interest in this context. Canine osteoarthritis is known to negatively affect the welfare of many dogs in the United Kingdom, but its consequences for their owners has not previously been described. The aim of this study was to use a qualitative methodology to explore the impacts on a dog owner that occur following their dog's diagnosis with osteoarthritis. Owners of osteoarthritic dogs based in the United Kingdom (UK) were recruited through veterinary practices to participate in semi-structured interview about life with their dog. Interviews were transcribed verbatim and thematic analysis was used to construct key themes. This publication describes the theme that focused on the impact(s) that the dog's condition had had on the life of their owner.

RESULTS

Forty owners of 35 dogs of a range of breeds and ages were interviewed. A wide range of negative impacts on the physical, mental and financial health of owners were described. Few had any prior experience of canine osteoarthritis, and owners of young dogs appeared to be particularly affected by the diagnosis. Owners detailed increasing worry over time about their pet's condition, frequently combined with a growing need to physically assist their dog. Sometimes this led them to seek information about, and purchase, adjunctive therapies and products. The dog's reduced mobility and need for medications progressively limited their own lifestyles and ability to have time away from their pet. Owners typically described a strong bond with their dog as a motivator to provide ongoing care.

CONCLUSIONS

The negative impacts on owners of caring for an osteoarthritic dog appear multi-faceted and may be sustained over many years, particularly if the dog is young at diagnosis. Owners may be highly motivated to improve their dog's mobility and to reduce the impact the condition has on their own lives, yet they may be unsure how to achieve this. Veterinary professionals should inform and support these owners as much as possible.

Association between Pet Ownership and Obesity: A Systematic Review and Meta-Analysis

Obesity is a major risk factor for lifestyle-related diseases, including cardiovascular disease, type 2 diabetes, and hypertension. Several studies have investigated the association between pet ownership and obesity, but the findings have been inconsistent. This systematic literature review and meta-analysis assessed the association between pet ownership and obesity. Using PubMed and Scopus, we overviewed the literature published until December 2019 and selected pertinent data for meta-analysis. Two independent reviewers extracted the data. Pooled relative risks (RRs) with 95% confidence intervals (CIs) for obesity were calculated using the random-effects model with inverse-variance weighting. The 21 included articles were cross-sectional studies. Five publications (nine analyses) that reported adjusted RRs for BMI ≥ 25 were included in the meta-analysis. No significant association existed between pet ownership and obesity (pooled RR = 1.038; 95% CI, 0.922–1.167; I² = 51.8%). After stratification by age group (children vs. adults), no significant association was detected (pooled RR = 0.844; 95% CI, 0.604–1.179; I² = 64.1% vs. pooled RR = 1.099; 95% CI, 0.997–1.212; I² = 25.2%). Similarly, no significant association was observed between dog ownership and obesity, indicating no association between pet ownership and obesity. However, no infer causation can be reported because all studies included in this meta-analysis were cross-sectional. Therefore, further prospective studies are needed.

Pets Are Associated with Fewer Peer Problems and Emotional Symptoms, and Better Prosocial Behavior: Findings from the Longitudinal Study of Australian Children

OBJECTIVE

To investigate the longitudinal association between pet ownership and children's social-emotional development.

STUDY DESIGN

Two time-points of data from the Longitudinal Study of Australian Children were analyzed for children at ages 5 (n = 4242) and 7 (n = 4431) years. The Strengths and Difficulties Questionnaire (SDQ) measured children's social-emotional development. Pet ownership status and type (dog, cat, other) as well as sociodemographic and other potential confounders were collected. Longitudinal panel regression models were used.

RESULTS

Overall, 27% of children had abnormal scores on 1 or more SDQ scales. By age 7, 75% of children had pets with ownership highest in single-child households. Owning any type of pet was associated with decreased odds of abnormal scores for emotional symptoms (OR, 0.81; 95% CI, 0.67-0.99), peer problems (OR, 0.71; 95% CI, 0.60-0.84), and prosocial behavior (OR, 0.70; 95% CI, 0.38-0.70), compared with non-pet owners. Dog ownership was associated with decreased odds of abnormal scores on any of the SDQ scales (OR, 0.81; 95% CI, 0.71-0.93). For children without any siblings, only the prosocial behavior scale was significantly associated with pet ownership (OR, 0.21; 95% CI, 0.07-0.66). In longitudinal models, cat-only and dog-only groups were associated with fewer emotional symptoms and peer problems compared with non-pet owners.

CONCLUSIONS

Early school age is an important period for family pet acquisition. Pets may protect children from developing social-emotional problems and should be taken into account when assessing child development and school readiness. Children without siblings may benefit most in terms of their prosocial behavior.

Slower, shorter, sadder: a qualitative study exploring how dog walks change when the canine participant develops osteoarthritis

Background

Dog walking may have multiple physical and mental health advantages, but not all dog owners appear to benefit. Dog health is a described barrier to dog walking activity, but specific causes and impacts of reduced exercise in owners of dogs with health problems have not previously been reported. The current study used a qualitative methodology to explore the impact of canine osteoarthritis on dog walking activity.

Methods

Owners of dogs with osteoarthritis living in the United Kingdom (UK) were recruited through veterinary practices for semi-structured interview about life with an osteoarthritic dog. Participants were asked to reflect on walks that they had taken with their dog before he/she developed osteoarthritis, and to describe how those walks had changed. Interviews were transcribed verbatim and thematic analysis was used to construct key themes.

Results

Forty owners of 35 osteoarthritic dogs were interviewed. Prior to their dog’s development of osteoarthritis, dog walking distance, speed and location were usually decided by the owner to satisfy the needs and enjoyment of dog and walker. A diagnosis of canine osteoarthritis led to both dogs and their owners altering the walks undertaken. Walks were typically slower, shorter and limited to locations where physical infrastructure, underfoot surface and gradients were perceived by the owner to be navigable by their dog. Most owners did not go on additional walks without their dog due to feelings of guilt and because walking without a dog was less enjoyable. Many owners described negative effects on their own physical health and diminished enjoyment of walking as a result of their dog’s condition.

Conclusion

Our research suggests that osteoarthritic dogs may reduce the walking exercise their owners are able or willing to undertake. Since osteoarthritis is a common condition in older dogs, this is an important finding for those advocating dog ownership as a positive public health intervention. Strategies may be needed to ensure that owners of dogs that develop physical incapacities can continue to enjoy the health benefits they previously associated with dog walking. Future studies investigating dog walking activity should ensure that the health status of the dog has been considered.

Dog ownership, the natural outdoor environment and health: a cross-sectional study

OBJECTIVES

Dog owners walking their dog in natural outdoor environments (NOE) may benefit from the physical activity facilitated by dog walking and from time spent in nature. However, it is unclear whether dog owners receive additional health benefits associated with having access to NOE above the physical activity benefit of walking with their dog. We investigated associations between dog ownership, walking, time spent in NOE and health and whether these associations differed among those with good and poor access to NOE and those living in green and less green areas.

DESIGN

Cross-sectional study.

SETTING

The Positive Health Effects of the Natural Outdoor Environment in Typical Populations in Different Regions in Europe project.

PARTICIPANTS

n=3586 adults from Barcelona (Spain), Doetinchem (the Netherlands), Kaunas (Lithuania) and Stoke-on-Trent (UK).

DATA COLLECTION AND ANALYSIS

We calculated access to NOE with land maps and residential surrounding greenness with satellite data. Leisure time walking, time spent in NOE and general and mental health status were measured using validated questionnaires. Associations were estimated using multilevel analysis with a random intercept defined at the neighbourhood level.

RESULTS

Dog ownership was associated with higher rates of leisure time walking and time spending in NOE (OR 2.17, 95% CI 1.86 to 2.54 and 2.37, 95% CI 2.02 to 2.79, respectively). These associations were stronger in those living within 300 m of a NOE and in greener areas. No consistent associations were found between dog ownership and perceived general or mental health status.

CONCLUSIONS

Compared with non-dog owners, dog owners walked more and spent more time in NOE, especially those living within 300 m of a NOE and in greener areas. The health implications of these relationships should be further investigated. In a largely physically inactive society, dog walking in NOE may be a simple way of promoting physical activity and health.

Promoting Outdoor Physical Activity for People and Pets: Opportunities for Veterinarians to Engage in Public Health

Regular physical activity (PA) is a health promoting behavior that transcends species. The collective evidence of a positive relationship between PA and health in both people and animals suggests that implementation of outdoor, dog-associated activities to increase PA may synergistically enhance both human and dog health. A systematic literature review was performed to identify research investigating objective, quantitative health outcomes in both dogs and people exercising together. Within the confines of the search, only 2 studies fulfilled the criteria for complete review. One study was administered through a veterinary clinic and another through a human health care provider. Both studies focused on obesity treatment, either for the dog or for both the dog and the owner. Collectively this work demonstrates the feasibility of simultaneously promoting health in both groups through PA; however there are limitations to the generalizability of the findings. Additional research is needed to further investigate the feasibility and effectiveness of PA promotion in primary care veterinary clinics as well as the use of animal-assisted PA promotion as a preventative, not just therapeutic, tool. As diseases that can be prevented, at least in part, by regular PA are now the leading causes of morbidity and mortality in developed countries, veterinarians have the potential to significantly impact not only the health of their patients, but also that of the public.

The association between dog ownership or dog walking and fitness or weight status in childhood

BACKGROUND

Health benefits of dog walking are established in adults: dog owners are on average more physically active, and those walking their dogs regularly have lower weight status than those who do not. However, there has been little research on children.

OBJECTIVES

This study aimed to examine the association between dog ownership or dog walking and childhood fitness or weight status.

METHODS

A survey of pet ownership and involvement in dog walking was combined with fitness and weight status measurements of 1021 9 to 10-year-old children in the Liverpool SportsLinx study.

RESULTS

We found little evidence to support that children who live with, or walk with, dogs are any fitter or less likely to be obese than those who do not.

CONCLUSIONS

This is an important finding, as it suggests that the activity that children currently do with dogs is not sufficient enough to impact weight status or fitness.

The Influence of Family Dog Ownership and Parental Perceived Built Environment Measures on Children's Physical Activity within the Washington, DC Area

Sedentary behavior and physical inactivity are significant contributors to youth obesity in the United States. Neighborhood dog walking is an outlet for physical activity (PA). Therefore, understanding the relationship between built environment, dog ownership, and youth PA is essential. This study examined the influence of dog ownership and parental built environment perceptions on children’s PA in the Washington, D.C. area. In 2014, questionnaires were mailed to 2000 parents to assess family dog ownership; children’s outdoor dog walking or playing; and parental perceived built environment measures. Chi-square analyses examined differences in parental perceived built environment measures between children with and without family dogs. The sample included 144 children (50% female; average-age 9.7 years; 56.3% White; 23.7% African-American; 10.4% Asian-American; 29.9% owned dog). Only 13% and 5.6% of the children walked or played outdoors with the dog daily, respectively. A significantly greater proportion (p-value < 0.05) of parents who owned dogs recognized and observed some home built environment measures (e.g., traffic speed on most streets is 30 mph or less) that were PA -promoting for their children. Findings suggest that dog ownership may provide more positive parental perceptions of the neighborhood built environment, which supports children’s outdoor PA through dog walking and playing.

Pet dogs and child physical activity: the role of child-dog attachment

BACKGROUND

Dog ownership has been associated with increased physical activity in children which in turn may mitigate childhood obesity.

OBJECTIVE

To measure the association between child-dog attachment and child physical activity and screen time.

METHODS

Cross-sectional study including 370 children (ages 4-10) who had pet dogs in the home. Parents completed the DartScreen, a web-based screener, before a well-child visit. Screener domains included child body mass index (BMI), physical activity, screen time and dog-related questions. The Companion Animal Bonding Scale (CABS) was used to measure child attachment to the dog. Clinic nurses weighed and measured the children. Associations between CABS, BMI z-score, screen time and physical activity were estimated.

RESULTS

CABS was strongly associated with time spent being active with the dog (F = 22.81, p < 0.0001), but not with BMI z-score or screen time.

CONCLUSIONS

A higher level of child attachment to a pet dog is associated with increased child physical activity.

A Birth Cohort Analysis to Study Dog Walking in Adolescence Shows No Relationship with Objectively Measured Physical Activity

Physical inactivity during childhood and adolescence is a serious health concern. There are few studies of the activity undertaken by adolescents when walking with the family dog, and the effect of this on objectively measured physical activity levels. Objective measures of physical activity using accelerometers were recorded at age 11–12, 13–14, and 15–16 years in the Avon Longitudinal Study of Parents and Children (ALSPAC) (ALSPAC, UK) birth cohort during the 2000s. Family pet ownership was collected retrospectively using a questionnaire at age 18 years, for the ages 7, 11, 13, and 15 years. In addition, approximate frequency per week of walks undertaken with dogs were also reported. Multilevel, multivariable modeling was used to investigate the relationship between dog ownership and dog walking status, and physical activity outcomes. There were a total of 4,373 complete data observations for use in 2,055 children. Reported participation in dog walking tended to increase during adolescence, as did dog ownership. The majority of who own dogs reported walking them either 2–6 times/week (range 39–46%) or never (range 27–37%). A small minority (7–8%) reported walking their dog every day. Most reported never walking any other dog either (94–87%). We found no evidence for an association between dog ownership or reported dog walking, and objectively measured physical activity (counts per minute, P = 0.3, or minutes of moderate-to-vigorous physical activity, P = 0.7) during adolescence. This study provides no evidence to support a relationship between adolescent dog ownership and physical activity, and demonstrates the importance of using objective activity measures and considering dog walking rather than just dog ownership.

Family Dog-Assisted Adapted Physical Activity: A Case Study

Purpose: The aim of this case study was to examine the individual effects of an adapted physical activity, animal-assisted intervention (APA-AAI) with the family dog on motor skills, physical activity, and quality of life of a child with cerebral palsy (CP). Method: This study used an A-B-A single-subject design. The assessment phase (phase A) occurred pre- and post-intervention. This consisted of standardized assessments of motor skills, quality of life questionnaires, physical activity (measured using the GT3X+ accelerometer) and the human-animal bond. The intervention (phase B) lasted 8 weeks and consisted of adapted physical activities performed with the family dog once a week for 60 min in a lab setting. In addition, the participant had at-home daily activities to complete with the family dog. Results: Visual analysis was used to analyze the data. Motor skill performance, physical activity, quality of life and human animal interaction gains were observed in each case. Conclusions: These preliminary results provided initial evidence that the family-dog can play a role in healthy lifestyles through APA-AAI in children with CP.

The effect of siblings and family dog ownership on children's independent mobility to neighbourhood destinations

OBJECTIVE

To investigate the effect of sibling age, gender and dog ownership on children's independent mobility and how this varies according to the destination visited.

METHODS

Parents reported whether their child had an older sibling; if the child and older sibling were of the same gender; the number of older siblings; if they owned a dog; and whether their child was allowed to independently travel to school, friends' or family house, park/oval/sporting field and local shop. Data were analysed for 181 children aged 8-15 years.

RESULTS

The strongest significant sibling effect for independently mobility to school, local shop and ≥3 destinations was for having an older sibling of the same gender (p≤0.05). For independent mobility to a friend's house and park, the strongest significant sibling effect was for having one older sibling (p≤0.05). Dog ownership was associated with increased odds of being independently mobile to ≥3 destinations (OR=2.43; 95%CI=1.03-5.74).

CONCLUSIONS

Parents may be more likely to grant children licence to travel to local places if they are accompanied by an older sibling or the family dog.

IMPLICATIONS

Understanding the effects of siblings and dog ownership on children's independent mobility will assist in identifying strategies through which independent mobility can be encouraged.

Dog walking among adolescents: Correlates and contribution to physical activity

PURPOSE

To assess the association of dog walking with adolescents' moderate-to-vigorous physical activity (MVPA) and body mass index (BMI), and identify correlates of dog walking.

METHODS/DESIGN

Participants were 12-17year-olds (n=925) from the Baltimore, MD and Seattle, WA regions. Differences in accelerometer-assessed minutes/day of MVPA and self-reported BMI (percentile) were compared among adolescents (1) without a dog (n=441) and those with a dog who (2) did (≥1days/week, n=300) or (3) did not (n=184) walk it. Correlates of (1) dog walking (any vs. none) among adolescents with dogs (n=484), and (2) days/week of dog walking among dog walkers (n=300) were investigated. Potential correlates included: demographic, psychosocial, home environment, perceived neighborhood environment, and objective neighborhood environment factors.

RESULTS

52% of adolescents lived in a household with a dog, and 62% of those reported dog walking ≥1day/week. Dog walkers had 4-5 more minutes/day of MVPA than non-dog-walkers and non-dog-owners. BMI was not associated with dog walking or ownership. Among households with dogs, adolescents who lived in objectively walkable neighborhoods were 12% more likely to walk their dog than those in less walkable neighborhoods. Among dog walkers, having a multi-family home, college-educated parent, lower perceived traffic safety, higher street connectivity and less mixed use were related to more days/week of dog walking.

CONCLUSIONS

Dog walkers had 7-8% more minutes/day of MVPA than non-dog walkers, and correlates of dog walking were found at multiple levels of influence. Results suggest multilevel interventions that include both environmental and psychosocial components to increase dog walking should be evaluated.

Built environment and active play among Washington DC metropolitan children: A protocol for a cross-sectional study

Background

Research has demonstrated that children who participate in active play are more likely to be physically active, thereby improving long-term health outcomes. Many adult studies have also shown that neighborhood built environments can encourage or discourage routine physical activity. Limited evidence has demonstrated that children who reside in neighborhoods with a built environment that is more inviting to active play exhibit lower overweight and obesity rates as well as an overall better state of well-being. This Built Environment and Active Play (BEAP) Study aims to develop a neighborhood playability rating system in the Washington, DC (DMV) area. Similar to walkability scores, these playability scores will estimate how affable a neighborhood is to active play. The BEAP Study will attempt to provide a broad view of factors influencing the level and type of active play among children.

Methods/Design

Using a cross-sectional design, the BEAP Study will collect data using a mail questionnaire administered to the parents and/or guardians of 2000 children aged 7-12 years residing in select DMV areas in October of 2014. Questionnaire data, including information on active play, home and neighborhood characteristics, parental perceptions, and sociodemographic characteristics will be merged through a geographic information system (GIS) with objective built environment measures in the participants’ neighborhoods. An ordered logit model will be used to regress an ordinal active play outcome on built environment exposure variables while adjusting for potential confounders. Upon the construction of the final model, predictor coefficients will be used as parameters in the scoring system to develop neighborhood playability scores.

Discussion

The BEAP Study intends to generate a neighborhood playability index by characterizing and quantifying children’s active play using parent-reported physical activity data in children, GIS data and built environment measures in participant neighborhoods. The BEAP Study will improve our understanding of the built environment and childhood playability relationship while also contributing to the body of evidence-based built environment and physical activity research.

Dog walking is associated with more outdoor play and independent mobility for children

OBJECTIVE

Dog ownership is positively associated with children's physical activity. It is plausible that dog-facilitated activity rather than dog ownership per se encourages children's physical activity behaviors. We examined relationships between dog walking and children's physical activity, and outdoor play and independent mobility.

METHOD

Cross-sectional survey data from the 2007 Perth (Western Australia) TRavel, Environment, and Kids (TREK) project were analyzed for 727 10-12 year olds with a family dog. Weekly minutes of overall physical activity and walking, local walking and outdoor play were collected from children and parents. Children's weekly pedometer steps were measured. Independent mobility was determined by active independent travel to 15 local destinations.

RESULTS

Overall, 55% of children walked their dog. After adjustment, more dog walkers than non-dog walkers walked in the neighborhood (75% vs. 47%), played in the street (60% vs. 45%) and played in the yard (91% vs. 84%) (all p ≤ 0.05). Dog walkers were more independently mobile than non-dog walkers (p ≤ 0.001). Dog walking status was not associated with overall physical activity, walking, or pedometer steps (p>0.05).

CONCLUSIONS

Dog-facilitated play and physical activity can be an effective strategy for increasing children's physical activity. Dog walking may provide a readily accessible and safe option for improving levels of independent mobility.

How might we increase physical activity through dog walking?: A comprehensive review of dog walking correlates

BACKGROUND

Physical inactivity and sedentary behaviour are major threats to population health. A considerable proportion of people own dogs, and there is good evidence that dog ownership is associated with higher levels of physical activity. However not all owners walk their dogs regularly. This paper comprehensively reviews the evidence for correlates of dog walking so that effective interventions may be designed to increase the physical activity of dog owners.

METHODS

Published findings from 1990-2012 in both the human and veterinary literature were collated and reviewed for evidence of factors associated with objective and self-reported measures of dog walking behaviour, or reported perceptions about dog walking. Study designs included cross-sectional observational, trials and qualitative interviews.

RESULTS

There is good evidence that the strength of the dog-owner relationship, through a sense of obligation to walk the dog, and the perceived support and motivation a dog provides for walking, is strongly associated with increased walking. The perceived exercise requirements of the dog may also be a modifiable point for intervention. In addition, access to suitable walking areas with dog supportive features that fulfil dog needs such as off-leash exercise, and that also encourage human social interaction, may be incentivising.

CONCLUSION

Current evidence suggests that dog walking may be most effectively encouraged through targeting the dog-owner relationship and by providing dog-supportive physical environments. More research is required to investigate the influence of individual owner and dog factors on 'intention' to walk the dog as well as the influence of human social interaction whilst walking a dog. The effects of policy and cultural practices relating to dog ownership and walking should also be investigated. Future studies must be of a higher quality methodological design, including accounting for the effects of confounding between variables, and longitudinal designs and testing of interventions in a controlled design in order to infer causality.

Children, parents and pets exercising together (CPET): exploratory randomised controlled trial

BACKGROUND

Levels of physical activity (PA) in UK children are much lower than recommended and novel approaches to its promotion are needed. The Children, Parents and Pets Exercising Together (CPET) study is the first exploratory randomised controlled trial (RCT) to develop and evaluate an intervention aimed at dog-based PA promotion in families. CPET aimed to assess the feasibility, acceptability and potential efficacy of a theory-driven, family-based, dog walking intervention for 9-11 year olds.

METHODS

Twenty-eight families were allocated randomly to either receive a 10-week dog based PA intervention or to a control group. Families in the intervention group were motivated and supported to increase the frequency, intensity and duration of dog walking using a number of behaviour change techniques. Parents in the intervention group were asked to complete a short study exit questionnaire. In addition, focus groups with parents and children in the intervention group, and with key stakeholders were undertaken. The primary outcome measure was 10 week change in total volume of PA using the mean accelerometer count per minute (cpm). Intervention and control groups were compared using analysis of covariance. Analysis was performed on an intention to treat basis.

RESULTS

Twenty five families were retained at follow up (89%) and 97% of all outcome data were collected at baseline and follow up. Thirteen of 14 (93%) intervention group parents available at follow up completed the study exit questionnaire and noted that study outcome measures were acceptable. There was a mean difference in child total volume of PA of 27 cpm (95% CI -70, 123) and -3 cpm (95% CI -60, 54) for intervention and control group children, respectively. This was not statistically significant. Approximately 21% of dog walking time for parents and 39% of dog walking time for children was moderate-vigorous PA.

CONCLUSIONS

The acceptability of the CPET intervention and outcome measures was high. Using pet dogs as the agent of lifestyle change in PA interventions in children and their parents is both feasible and acceptable, but did not result in a significant increase in child PA in this exploratory trial.

Dogs motivate obese children for physical activity: key elements of a motivational theory of animal-assisted interventions

Background: There is empirical evidence that the presence of a companion animal can have a positive impact on performance. The available evidence can be viewed in terms of differing hypotheses that attempt to explain the mechanisms behind the positive effects. Little attention has been given to motivation as a potential mode of action with regards to human-animal interactions. First we give an overview of evidence that animals might promote motivation. Second we present a study to examine the effect of a therapy dog on exercise performance in children with obesity.

Methods: Twelve children, aged 8–12 years old, were randomly assigned to two groups in a crossover design: dog-group and human confederate group. Several types of physical activities via accelerometer and subjective ratings of wellbeing, satisfaction, and motivation were assessed. Data were analyzed using analysis of variance for repeated measures on one factor.

Results: The main effect of condition was significant for all performance variables. There was less passive behavior and more physical activity for all performance variables in the presence of the dog than in that of the human confederate. Between dog- and human- condition there was no difference in the subjective rating of motivation, wellbeing, or satisfaction.

Discussion: The results demonstrate that the presence of a therapy dog has the potential to increase physical activity in obese children. Task performance as a declarative measure was increased by the presence of the dog in comparison to a human confederate, but self-report measures of motivation, satisfaction or wellbeing did not differ between the two conditions. Therefore, it stands to reason that a dog could trigger implicit motives which enhance motivation for activity. The results of our study indicate the potentially beneficial effect of incorporating dogs into outpatient training for obese children.

A cross-sectional study of frequency and factors associated with dog walking in 9-10 year old children in Liverpool, UK

Background

Owning a pet dog could potentially improve child health through encouraging participation in physical activity, through dog walking. However, evidence to support this is limited and conflicting. In particular, little is known about children’s participation in dog walking and factors that may be associated with this. The objective of this study was to describe the participation of children in dog walking, including their own and those belonging to somebody else, and investigate factors associated with regular walking with their own pet dog.

Methods

Primary school children (n=1021, 9–10 years) from a deprived area of Liverpool were surveyed during a ‘fitness fun day’ as part of the SportsLinx project. The ‘Child Lifestyle and Pets’ survey included questions about pet ownership, pet attachment, and dog walking. Multivariable logistic regression models were used to investigate factors associated with walking any dog, or their own dog, several times a day or more, including level of attachment to the dog, dog type, and sociodemographic factors.

Results

Overall, 15.4% of children reported walking with any dog (their own or belonging to a friend or family member) ≥ once daily, 14.1% several times a week, 27.6% ≤ once a week, and 42.8% never. Dog owning children (37.1% of the population) more often reported dog walking ‘several times a week or more’ (OR=12.30, 95% CI=8.10-18.69, P<0.001) compared to those without a dog, but were less likely to report other walking without a dog. The majority (59.3%) of dog owning children indicated that they usually walked their dog, with 34.6% reporting that they walked their dog ≥ once daily. Attachment score was highly associated with the child reporting walking their dog (lower score=higher attachment; OR=0.93, 95% CI=0.89-0.96, P<0.001). There was no evidence that gender, ethnicity, sibling status or deprivation score was associated with dog walking. Children that reported owning Pit Bulls were more likely to report friends walking with their dog than those owning non-Pit bull types (OR=10.01, 95% CI=1.52-65.76, P=0.02, respectively).

Conclusions

Promotion of supervised walking of suitable pet dogs may be an opportunity for increasing physical activity in 9–10 year old children. The identification of stronger attachment to dogs regularly walked is similar to findings in adult studies.
