I had to think of a catchy line that would attract the attention of forum animal lovers

. Have had an animal living in my house for like 4 years now of questionable genetic background--even the vets are stumped. The bitch is smarter than Wyle E Coyote, more focused than a jungle cat and nearly as fast as a greyhound (caught the business end of a full-stride antelope in the hills a year ago).
What are your thoughts on breed? I'm sure it's a mix, of what primary animals? I'm thinking the bone structure looks alot like a catahoula, with a rottweiler mix.
