Phenotypic Characteristics Associated with Shelter Dog Adoption in the United States

The objective of this study was to identify phenotypic characteristics of dogs predictive of adoption after being received into a shelter. Individual dog records for 2017 were requested from shelters in five states that received municipal funding and utilized electronic record keeping methods. Records from 17 shelters were merged into a dataset of 19,514 potentially adoptable dogs. A simple random sample of 4500 dogs was used for modelling. Variables describing coat length, estimated adult size, and skull type were imputed from breed phenotype. A Cox proportional hazard model with a random effect of shelter was developed for the outcome of adoption using manual forward variable selection. Significance for model inclusion was set at alpha = 0.05. Dogs from shelters in the North were more likely to be adopted than dogs from shelters in the South (hazard ratio (HR) = 3.13, 95% C.I. 1.27–7.67), as were dogs from Western shelters versus those from Southern shelters (HR = 3.81, 95% C.I. 1.43–10.14). The effect of estimated adult size, skull type, and age group on adoption were each modified by time in the shelter (p < 0.001). The results of this study indicate that what dogs look like is predictive of their hazard for adoption from shelters, but the effect of some characteristics on hazard for adoption depend on time in the shelter. Further, this study demonstrates that adopters prefer a certain phenotype of shelter dog including those that are puppies, small sized and not brachycephalic, when accounting for time in the sheltering environment.

Difficulties in Making the Ethically Correct Choice in the Management of a Case of Proven Dangerousness of a Shelter Dog

The management of shelter dogs whose dangerousness to people has been verified is an aspect of considerable importance as it assesses animal welfare, public health, and the management of human and economic resources. In this paper, we briefly discuss the case of a large sized male dog that had bitten people several times and was declared to be at high risk of causing danger. Despite a behavioral rehabilitation program, the initial evidence of dangerousness remained unchanged, thus, there was no possibility of putting the dog up for adoption. This clinical case is an example of how conflicting it is for a behaviorist to choose ethically when considering euthanasia and animal welfare.

Characteristics and Adoption Success of Shelter Dogs Assessed as Resource Guarders

Some domestic dogs aggressively guard resources. Canine resource guarding impacts public health through dog bites and affects dog welfare through adoption and euthanasia policies at animal shelters. However, little is known about the demographic characteristics and adoption success of dogs assessed as resource guarders during shelter behavioral evaluations. I reviewed nearly five years of records from a New York (NY) SPCA and categorized 1016 dogs by sex; age; size; reproductive status; and resource guarding. I then examined how these characteristics influenced the returns of dogs by adopters. The prevalence of resource guarding in this shelter dog population was 15%. Resource guarding was more common in adult and senior dogs than in juvenile dogs; and it was more common in small and large dogs than medium-sized dogs. Spayed females were more likely than intact females to guard food; neutered males and intact males did not differ in their likelihood of food guarding. Most dogs identified as resource guarders showed mild to moderate guarding. Severe guarders were more likely to be returned by adopters; although almost all were eventually re-adopted and not returned to the shelter. Data presented here provide the most comprehensive description of resource guarders in a shelter dog population and show the successful re-homing of most.

The effect of adopter’s gender on shelter dog selection preferences

A retrospective analysis of dog adoption records was performed with the aim to determine the differences in preferences of male and female adopters in the Czech Republic. From January 1, 2010 to December 31, 2016, 955 dogs were adopted out of a selected shelter. Significantly (P = 0.03) more dogs were adopted by women than by men (52.6% vs 47.4%, respectively). No preference (P = 0.06) for adopting a dog of the same or opposite sex as the adopter’s was found. Women adopted more (P = 0.02) small dogs and men more (P = 0.004) large dogs, while the adoption rate of medium dogs did not differ (P = 0.16) between men and women. Significantly more (P = 0.05) older dogs were adopted by women than by men. With the exception of brown dogs (adopted more often by women) and black dogs with dark markings (adopted more often by men), dogs with different coat colors were adopted equally by men and women. No difference was found between the ratio of crossbred and purebred dogs adopted by men and women. This study fills gaps in scientific knowledge on adopters’ preferences. Women are more willing to adopt dogs including those that may require special care (older dogs). However, women are less likely to adopt large dogs. The lower number of male adopters may be the reason why large dogs are often reported to be difficult to rehome. To remedy this, shelter operators should explore ways how to address men if they have large dogs available for adoption.

Pyloric Leiomyoma: Behavioural Aspects in a Shelter Dog

The present report describes a case of pyloric wall leiomyoma in a shelter dog with a history of vomiting, pica, licking and chewing the walls of the kennel. The clinical, radiological, ultrasound, hematological and blood chemistry examinations showed no abnormalities. A compulsive oral disorder was diagnosed and treatment with behaviour therapy instigated. The compulsive oral behaviours stopped following behaviour therapy, however, the vomiting persisted, suggesting the need to proceed with further diagnostic exams. The ultrasound examination, repeated after 6 months, had revealed the presence of a hypoechoic mass (3.52 cm) in the pyloric-antrum obstructing the gastric outflow. Following gastric dilatation the mass was surgically excised. Histological examination revealed a pyloric leiomyoma. In clinical practice this case highlights the importance of gastrointestinal diseases in the development of behaviour changes related to pica.
