A multivariate discriminate analysis of behavioral measures in genetically nervous dogs

Reproductive ability of a cloned male detector dog and behavioral traits of its offspring

In 2007, seven detector dogs were produced by somatic cell nuclear transfer using one nuclear donor dog, then trained and certified as excellent detector dogs, similar to their donor. In 2011, we crossed a cloned male and normal female by natural breeding and produced ten offspring. In this study, we investigated the puppies' temperaments, which we later compared with those of the cloned parent male. The results show that the cloned male had normal reproductive abilities and produced healthy offspring. All puppies completed narcotic detector dog training with a success rate for selection of 60%. Although the litter of cloned males was small in this study, a cloned male dog bred by natural mating produced puppies that later successfully completed the training course for drug detection. In conclusion, cloning an elite dog with superior genetic factors and breeding of the cloned dog was found to be a useful method to efficiently procure detector dogs.

Familial vulnerability for experimental neurosis

This summary review of work from one specialized laboratory provides background for the ensuing theoretical discussion concerning experimental neurosis in one inbred strain of purebred pointers. These animals respond selectively to negative reinforcements provided adventitiously in the laboratory environment. The inherited vulnerability of this neurotic strain is contrasted with the high "immunity" of a parallel line in the same laboratory environment.
