Blackmouth cur question

They don't go back to Leopard Hounds, when I say Leopard I mean what is now called Catahoulas before the bay pen and color breeding fad. As far as the yellow dogs I would say it was a case of pretty is as pretty does, whatever crosses began to produce Yellow and yellow black muzzled dogs was well thought of therefore somewhat sought after. As for myself I have never worried about what made them up I was just glad to have stumbled on some I could get along with and concentrated on the ancestors I believed to have produced the traits I liked. With this pattern of thought I haven't really researched their original origin nearly as thoroughly as Bob has he would know far more about the original origins.
