One of the things I always wondered about. I have always believed that the Catahoula cur & the Leopard cur had common ancestors but were bred for different purposes.
Richard McDuffie & a few others collected up a bunch of curs that would tree & begin linebreeding them for coon hunting. They called them Leopard curs.(now know as leopard hounds)
Down in the deep south people bred their dogs to work livestock & a couple of different breeds evolved. The Catahoula & the Blackmouth. The old Howard Carnathon blackmouths looked to me like they had bulldog in them. The old time Catahoulas that were working dogs were real leggy. Not the heavy headed bulldog looking Catahoulas that I see alot of today.
Mostly over in Texas the working blackmouths are leggy built dogs that can cover ground & not wear out.
All three of these breeds probably had common ancestors, they were just bred for different purposes.
Just speculation on my part & worth what you paid for it.
