Thanks, CD, but are you sure that is an American Leopard Hound? I know the coonhound people have been saying the ears are kind of short for a coonhound, but that looks like some kind of terrier.
Not exactly, it's all very confusing, but the American Leopard Hound is the same as the former Leopard Cur, and has now been recognized as the seventh variety of coonhound by the UKC. I think you got that from Wikipedia, which is even more confused than I am. I have a bunch of photos of Leopards on trees, but none stacked.
How this animal is related to the Catahoula, which is a cattle dog, not a hunting hound, isn't entirely clear to me.
