Impact of Human Presence and Visual Access on Barking Behavior in Shelter Dogs

Shelters can be stressful for dogs due to lack of predictability and control, social isolation, and busy environments. Providing dogs with more social opportunities and environmental predictability may improve their welfare. Barking may indicate stress and contribute to noise levels that are harmful to dogs and people. We investigated the impact of human presence and line of sight on barking. We manipulated line of sight by partially removing a crate barrier to allow the dogs visual access to other dogs and a better view of the room. We collected data on barking on 17 focal dogs as well as overall barking in the room during pre-treatment (no visual access), treatment (visual access), and post-treatment (no visual access) and noted if a person other than the observer was in the room. We found that in-room barking was significantly higher when a person was in the room (Wilcoxon Signed Ranks Test, Z= -4.048, p \u3c .001). Based on these results, shelters should consider limiting the human activity in the room to reduce noise levels. Since barking did not significantly increase with the addition of visual access, shelters may also consider providing the dogs visual access as a way to allow beneficial social interaction

#6 - Implications of Visual Social Access on the Welfare and Behavior of Shelter Dogs

Given the large number of dogs housed in animal shelters each year, it is important to consider how the shelter environment impacts dog welfare. The shelter environment is stressful due to factors such as excessive noise, lack of predictability and control, and social isolation. Social isolation in shelter dogs has been found to increase abnormal behavior and aggression and lead to poorer adoption outcomes. While social housing is ideal, it requires resources not available to all shelters. Providing visual access to other dogs is a relatively easy environmental modification that increases social opportunities and allows for more predictability and control over the environment, potentially improving welfare. To investigate the impact of visual access on the behavior of dogs, we used a within-subject design, conducting 5-min focal observations four times weekly before, during, and after visual access was provided by partially removing a barrier between crates at a suburban dog shelter. Our preliminary analysis of 17 subjects using non-parametric Friedman’s Tests (alpha = .05) found no significant difference between phases in regard to anxiety behaviors (χ2 (2) = .50, p = .78), frustration behaviors (χ2 (2) = .51, p = .77), time spent in the front of the crate (χ2 (2) = 4.50, p = .11), self-directed behaviors (χ2 (2) = 1.86, p = .40), resting behaviors (χ2 (2) = 4.59, p = .10), or vocalizations (χ2 (2) = 4.59, p= .10). The absence of an increase in vocalizations during visual access may encourage shelters to implement this change. However, the lack of a decrease in anxiety or frustration behaviors may indicate that visual access alone is insufficient for providing welfare benefits and that shelters should prioritize increasing social contact in dogs through playgroups or group housing.
