there is deffinatly a difference, i have owned both. the american leopard cur is more houndy, colder nosed, fast, and most are open mouthed on track. they come colored same as catahoulas tho. leopard and black and tan. i think i have a pic. of my old black and tan leopard i will try and post later.
I like them! but they are same as every other breed, UKC recognized them as a breed, and the price went thru the roof and hence forth breeding for$$$. but there are some good uns out there just do your home work. i would defenitly give one a try. my buddy bought theone i used to have and he is totaly silent in track, and built about as good as you can get.
The leopard cur and leopard hound are the same. The best I can decribe them is that they are somewhere between a hound and a catahoula. They are cold nosed and were bred for hunting. Most are open on track. The catahoula and the leopard cur/hound are two different breeds.
If I liked to hunt catahoulas I wouldn't hesitate to breed in some Leopard cur (bred for bear and boar) into the catahoula. On average I believe that I would get better nose, hunt and stick ability if I were wanting long range track dogs.
Right now there is a power struggle between the folks from the older days who want to continue calling them the leopard cur and others who here lately call them leopard hounds. Don't know why they want a leopard hound when we already have the Bluetick hound.
The mtn cur is the same in that they are somewhere in the middle between curs and hounds. They were bred to hunt all kinds of game and not to work cattle but they are good at working cattle if trained to do so.
Back in the old days the plott hound was known as a plott cur as well as a plott hound. Now all are known only as a plott hound.
