Still, even if black dog syndrome is "trumped-up" as Inglis-Arkell suggests, it's still important to consider the aesthetic qualities that make some dogs more likely to be adopted than others, so that we can become more aware of how little those aesthetic qualities actually matter. All shelter dogs need homes, and all shelter dogs deserve to find them. If a dog is relegated for one reason or another -- be it because of age, size or (most commonly) breed -- then it's lucky that volunteers pick up on related adoption trends.
That's especially true if it prompts shelters to take even greater pains to find animals loving families, as has often been the case in response to black dog syndrome. So even if the bias against black dogs is really just a myth, it's not entirely without value: black dog syndrome can get us thinking about what we really want in our pets, and it can help people see animals for who they truly are -- without regard to color.
