I work w/ our local animal shelter(the sweetie we adopted last Tuesday is snuggling next to me) & sadly black dogs are the least adopted group.
Probably because so many people have light colored upholstered furniture they don't want to deal with a black dog that sheds.
I just had a black poodle as a rescue foster that I placed in a new home Sunday...recent Air Force widow (and AF vet herself) who had two other black poodles.
