I can't answer this question, because I have no breed that I dislike, including those that aren't any particular breed at all!! I am a DOG LOVER and proud of it!!!
If your question were phrased a bit differently, and you asked which breed I would be most likely "not" to get, then I might be able to answer, but I have to say, if there is an opening in my house, I'd take any dog that needed me more than I needed it! Small, large, middlesized, I love them all!!! :)
