My understanding, until recently, was that black dogs or dogs with dark faces tended to stay longer in shelters because typically shelters have poor lighting and it’s harder to make the connection if the face/expression is more difficult to see. However, I recently read a post on Patricia McConnell’s blog where she talks about some studies that indicate breed/type, not color, is what primarily affects people’s perceptions of dogs.
[I]I just read an interesting blog on the ASPCA site about the issue, written by Dr. Emily Weiss. In it she recounts the result of a study done by PhD psychologist Lucinda Woodward et al, and published in Society and Animals in early 2012. In summary, they found that breed had a significant effect on participant’s perception of the dogs, but color did not. As a matter of fact, in a study looking at breed versus color effect, black labs were rated as significantly more friendly, less dominant and more submissive dogs of dogs of seven other breeds, with only the Golden retriever rated more highly. (The breeds were: Border collie, Boxer, German shepherd, Golden retriever, Black Lab, Pit bull, Standard Poodle and Rottweiler.)
This is not surprising when you think of it, given that black labs are the most popular breed in the U.S. last I looked. (Which in itself should give us all pause about the “black dog syndrome.”)
In addition, in a related study that focused on color and size in just one breed, all black poodles were judged to be friendlier than all white ones (and small white poodles were categorized as the least friendly!). These results suggest that color might not be as important a factor as we have assumed. Rather, the fact that so many black dogs hang out for long periods in shelters may be attributed to the fact that there are simply more of them.
Clearly we need a lot more research on this topic. Although this study is interesting, and I would argue important, in that it gets us into a conversation about what makes dogs attractive to people (which could help shelters place more dogs), it is just one study. It’s conclusions are indirect: just because a group of people rated some dogs as more friendly than others doesn’t mean they would necessarily adopt them from a shelter. But it is a good start.
