Pluto and Goofy are most certainly both cur dogs. Pluto is a high yeller simpleton, lives to please and whatever is needed he give it a college try. I've seen Pluto tree animals, flush birds, point, retrieve, track and so forth. He got used as a bird dog more oft than not when he was a using dog, but only because that has always been a dog sport that Americans find mainstream. I do believe I remember him being a cow dog in one Mickey Mouse short.
Goofy is absolutely a standard Black and Tan cur! He's "goofy", awkward and clumsy, but ultimately always reliable and noble. His Nearest costar aside from Mickey Mouse is most often Clarabel the cow and is often animated dancing with Clarabel or otherwise engaged in shenanigans involving saving her in early black and white toons where he's prominently featured.
Throw all this in with the knowledge that ol Walt carried a laymans knowledge of Florida and the people of the central swamp country. He inevitably crossed paths with plenty of crackers and their curs! The evidence points that there's no denying, they are curs!!!
