Some people call catahoulas lepord curs but there is a seperate breed of dog that was known as the American lepord cur until a few years ago when the registry changed the name to American lepord hound so they could competition coon hunt.
The lepord cur/hound is a bit different from the catahoula in appearance and how they act. They can have a thick double coat of hair, some are pretty bushy, often have a hound appearance, colder nose and a bawl mouth.
