Animal shelters are stressful environments for dogs and a plethora of research has been conducted on interventions aimed at improving the welfare of these animals. One type of intervention is social interaction, either between dogs and people or dogs and conspecifics. To investigate the types of social interaction dogs engage in and the impact of that contact on their welfare, 12 dogs were enrolled to participate in group sessions with other dogs, supervised by staff, in a shelter setting. There were three, 15-minute sessions per day across three days in which groups of two to four dogs were observed and recorded on video. These videos were then analyzed per dog for three types of interactions: dog-dog, dog-human, and dog-environment. It was found that the dogs spent significantly more time engaging with the staff members in the room than with conspecifics or the environment. Physiological measurements, including cortisol and S-IgA levels, were taken using urinary and fecal samples obtained both in the morning prior to these interaction sessions and after the final interaction of the day. No significant correlations were found between the amount of time that the dogs spent in each type of interaction and dogs’ cortisol or S-IgA levels. However, smaller statistical effects suggest that human interaction may correspond with decreased stress the day after interaction while conspecific interaction may be related to increases in stress the following day. Overall, these findings suggest that social interaction, particularly with people, may be beneficial, and should be further explored as a method to enhance the well-being of shelter dogs.

Personality testing in dogs has become a controversial topic in the dog community in the last few years. These assessments have been used among owners, shelters, working dog trainers, breeders, and researchers to identify patterns of behavior that may lead to insight about a dog’s personality. Due to inconsistencies in terminology and validity testing, these personality tests have lost a notable amount of credibility. Focusing on questionnaire and behavioral based testing, this literature review aims to evaluate the significance of personality testing within the dog community. Each assessment will be analyzed for measurements and validity, as well as potential drawbacks and benefits. Four prominent personality assessments will be discussed in depth. These assessments include C-BARQ, DPQ, SAFER, and VIDOPET. I advocate for a mixed assessment model approach and highlight the benefits of expanding personality testing into genetic research.

Animal shelters can be stress-inducing environments for dogs because of the noise, social isolation and unpredictable housing (Hennessy et al., 2020). Dog enthusiasts and researchers alike have found that social interaction can help alleviate stress in dogs. The aim of this study was to understand dogs’ interaction preferences to improve their welfare in animal shelters. We hypothesized that there would be statistically significant differences between both the time dogs spent in dog-dog and dog-human interactions. The dogs’ interaction preferences were operationalized as the percentage of their play time they spent in dog-dog, dog-human and dog-environment interactions. A total of twelve dogs from the Animal Humane Society (AHS) in Golden Valley, Minnesota shelter participated as subjects in the study. The study ran for two weeks, and there were 2 sessions of 15 minute playgroups recorded at 9:00 AM, 11:40 AM and 2:20 PM. Each playgroup consisted of two to four dogs. We found statistically significant differences between the percentage of each dog’s individual time they spent in dog-human interactions, which is supported by the literature. Differences between the percentage of each dog’s time in dog-dog interactions were nearly, but not quite statistically significant. Further research is needed to determine if age, size and breed contribute to the dog’s interaction preferences. More research is also needed to determine whether individual differences in preference for dog-dog interaction exist between dogs, and how this knowledge can be applied to improve dogs’ welfare in shelters. Our research suggests that shelters should continue to provide dogs with play time to interact with humans, as it is helpful in alleviating the impact of environmental stressors.
