Study of ingredients and nutrient composition of commercially available treats for dogs

Reporting perceived capability, motivations, and barriers to reducing treat feeding amongst dog and cat caregivers

Obesity remains a significant concern for dogs and cats, and reducing or eliminating treats is commonly recommended as a strategy for weight management. Caregivers can struggle with adherence to such dietary recommendations. Previous research suggests caregivers are reluctant to reduce treats but there is limited understanding of the underlying factors contributing to these behaviours and decisions. The objective of this study was to explore caregivers' motivations and barriers to reducing treat feeding, and their reported capability to do so. An online questionnaire including multiple choice and Likert scale questions was disseminated to dog and cat caregivers (n=1053) primarily from Canada and the USA from September to November 2021. Caregivers commonly expressed a wide range of motivations to reduce treat feeding with their pet, though barriers to reducing treat feeding were less defined. Changing their pet's routine was a reported barrier by more than 30% of respondents and was predictive of caregivers finding reducing treat giving to be difficult (OR=1.67, p=0.017). Results from multivariable logistic regression also revealed that caregivers who consider their companion animal to be obese as more likely to perceive reducing treats to be difficult. The results highlight the role of treats in the relationship and routine of caregivers' and their pets, and the importance of considering the individualised needs and circumstance of the caregiver and pet in veterinary discussions surrounding reducing treat feeding. Identifying these perspectives can improve self-efficacy with veterinary nutrition recommendations surrounding treats.

Dog caregivers' perceptions, motivations, and behaviours for feeding treats: A cross sectional study

Treats are commonly fed by most dog caregivers and can constitute a significant proportion of a dog's diet, potentially contributing to obesity. Feeding aspects related to treats specifically, remain underexplored. An e-survey was voluntarily completed by 716 dog caregivers predominantly from Canada and the USA to identify and describe caregivers' perceptions, motivations, and behaviours surrounding treats, and factors that influence decisions about feeding treats. Survey responses were analyzed using descriptive statistics, chi-square tests, Kruskal-Wallis one-way ANOVA, and Wilcoxon signed-rank tests. Multivariable logistic regression analyses were performed to analyze (1) measurement methods associated with monitoring treat intake, and (2) frequency of feeding different types of treats with perceiving dog as overweight/obese. Most caregivers considered the term 'treat' in a nutritional context, but respondents expressed mixed perceptions of how they consider treats in relation to their dog's primary diet. Alongside training and sports activities, aspects relating to the human-animal bond were highly reported to influence decisions surrounding treats. Most respondents were motivated to provide treats because it makes their pet happy, and to strengthen the bond with their dog, and nearly 40% of caregivers frequently feed treats to show love to their dog. Human food and table scraps were frequently fed by 30-40% of caregivers and feeding human food weekly was predictive of caregivers perceiving their dog to be overweight/obese (OR=2.24, p = 0.007). Caregivers estimated treats to account for a median of 15% of their dog's total diet, based on estimated quantity. Caregivers who reported using a measuring cup/scoop to measure their dog's treats were more likely to monitor their dog's treat intake (OR=3.38, p = 0.002). Most caregivers monitor their dog's body condition (60%) or consider their dog's recent activity level (43%) to decide on the amount of treats to feed; only 22% of caregivers reported veterinary advice to support their decisions on the amount of treats to feed. Findings from this research offer new insights to dog caregiver feeding habits and their perceptions of treats in relation to the canine diet. These results can be used to inform veterinary counselling strategies and caregiver education initiatives to promote animal health and well-being.

Using bioelectrical impedance analysis for modeling regression and predicting body fat accumulation in dogs in East Thailand

Background and Aim: Obesity in dogs leads to several health problems, such as premature death, and contributes to other diseases. Recently, body fat percentage has been considered to represent the body condition of dogs, and bioelectrical impedance analysis (BIA) is the most effective method for accurately measuring body fat in dogs. In Thailand, information on the body condition of dogs is limited, and there is no standard body fat level for Thai or mongrel dogs. This study was designed to evaluate and analyze the body fat percentage in dogs through BIA using a handheld instrument. The results of this study can help enhance the quality of life and health of dogs and aid in setting a standard body fat level for Thai or mongrel dogs. Materials and Methods: The body fat percentage of 340 Thai and mongrel dogs in East Thailand was measured in the standing position, and the body condition score (BCS) (range, 1–5), sex, sterilization status, age, type of diet, and lifestyle were recorded. A linear regression model was developed to compare the variables and the predicted body fat percentage, and multiple linear regressions were used to analyze the factors for body fat increment. Results: The linear regression model used to estimate the percentage of body fat (y) for each BCS (x) was y = 0.84 + 8.36x (R2 = 0.7219; p < 0.0001); the average body fat percentage was 27.52% for all studied dogs; specifically, 24.83% for the Thai Bangkaew, 26.42% for the Thai Ridgeback, and 27.65% for mongrels. The median body fat percentage was significantly higher in female than in male dogs. We found that as age increases, body fat percentage also increases; this increasing trend begins at the age of 5 years. However, increasing the level of activity and decreasing meal frequency leads to an increase in body fat percentage in neutered male dogs. Conclusion: The average body fat percentage of dogs in East Thailand is 27.52% and this value is expected to increase when these dogs reach the age of 5 years. BIA is a valid and effective measurement tool for detecting the body fat percentage in dogs.

Owners' views of canine nutrition, weight and wellbeing and their implications for the veterinary consultation

OBJECTIVES

To investigate owners' views around canine nutrition and wellbeing, how these beliefs may differ according to the weight status of the dog and the implications for owner support approaches.

MATERIALS AND METHODS

A researcher-mediated questionnaire collected quantitative and qualitative data via structured interviews with dog owners (n=147) attending a country park in the East Midlands, UK, with a specific focus on views around canine nutrition and wellbeing.

RESULTS

Forty-four percent of owners cited "past experience" when determining what to feed, and only 9% of owners cited the veterinarian as a source of this information. When comparing chosen verbal description versus non-sequential body condition score images of the dog, only 22% of owners with overweight animals matched perceived verbal and visual appraisals, compared with 89% of owners of ideal weight dogs. Owners cited a good diet and regular exercise as important factors for canine wellbeing, but companionship with other dogs as the least important factor.

CLINICAL SIGNIFICANCE

Owners report being aware of the important association between canine nutrition and wellbeing, but their considered importance of factors influencing dog wellbeing may be influenced by their perceived weight status of the animal. Veterinarians may need to reframe owner discourse such that there is more routine discussion around weight and nutrition at every consultation. Furthermore, the use of non-sequential body condition score images could be a useful tool for a more considered opinion of canine weight status by owners.

Microscopic examination of dog chews: correlation of histological findings to product labeling

The purpose of this study was to use routine morphologic-based staining techniques to examine the histology of commercially labeled rawhide and rawhide-free dog chew products and compare the results to the product labeling. Ten dog chew products were examined by light microscopy using hematoxylin and eosin and Masson's trichrome stains. The products were labeled by the manufacturer as rawhide, beef hide, beef chew/rawhide free, and rawhide free. Four of the products were composed of two separate materials, a main chew roll and a second substance (filler) which was coated on or between the layers of the main chew roll. These materials were processed independently. Microscopically, a variety of tissues and materials were identified including collagen, skeletal muscle, fat, plant material, and starch. The products and their fillers were separated into four distinct groups based on microscopic appearance. The components identified in eight of the products appeared consistent with the product labeling. Two products labeled as rawhide free appeared similar to the dermis and this was inconsistent with product labeling. Masson's trichrome stain was not helpful in distinguishing tissue types in the tested products and this may have been due to the heat processing the products underwent during manufacturing. Bacteria and/or fungi were identified by microscopy in the H&E stained sections in four rawhide-free products.

Understanding obesity among companion dogs: New measures of owner's beliefs and behaviour and associations with body condition scores

This research aimed to improve our understanding of how owners' beliefs and behaviour are associated with obesity in companion dogs. To do this, we employed new theoretical frameworks and integrated previously reported measures to curate a collection of brief, user-friendly self-report measures to assess owner factors. The reliability and validity of these was examined in two phases of empirical research, each with a cross-sectional questionnaire design that also examined the validity of assessing body condition score (BCS) from photographs submitted by owners. Phase 1 (n = 47 dog owners from France) found that the brief owner-report measures correlated with the long-form measures (all correlations except one exceeded r = 0.70). BCS as coded from photographs were highly correlated with a vet's assessment of the same dogs (r = 0.67). Phase 2 (n = 3339 dog owners from France, Germany, the UK, Italy, and Russia) investigated which measures are associated with obesity among companion dogs. Perceptions of the dog's vulnerability to the threat of obesity, perceived weight status, perceived costs associated with ownership, normative beliefs about feeding, social support from friends, and being in the precontemplation stage of change predicted BCS alongside demographic factors (e.g., dog's age, neutered status). Taken together, the findings provide a method for assessing a wide range of factors that may be associated with obesity among companion dogs and point to potential targets for interventions designed to reduce obesity.

A Survey of Dog Owners' Attitudes toward Treats

Commercially available dog treats have become very popular and a common part of the pet's diet, yet very little is known about peoples' opinions and feeding habits; therefore, a survey was shared on a popular social network.Most of the self-selected interviewed owners (n = 1833, 83%) use treats regularly, mainly to reward their dog's behavior or during training-sports activities. Owners usually buy several types of treats, of which biscuits and dental care sticks are the most common, and usually hand out one to five pieces to their dogs every day. Most owners read the labels of the treats to seek the ingredients list and the claimed health benefits; contrarily, many owners look for non-nutritional values, such as flavor (n = 321, 18%), brand (n = 72, 4%) or shape (n = 46, 3%). Seventy-five percent of the owners (n = 1369) follow the feeding instructions provided by the producers on the label.Treat feeding is a common practice among dog owners and there is great variability among regimens (e.g., types and quantities provided). Understanding the owner's attitudes could help veterinarians educate them to manage treats in the dog's diet.
