i took it to mean the original catahoulas... I guess it all depends on what catahoula definition ya read but from what i have read they came from war dogs "mastiff and greyhound x red wolf" I didnt get into questioning to much....
that's my understanding of their ancestry too, but i dont know if i'm buying his story about the dog "having more mastiff blood". kinda like if somebody had a registered one with a flag tail and they said "this line carries more of the red wolf blood" seems like a long way back to be showing up now. i'm sure you could breed that size back into them by just crossing big to big, but even then could you say it came from the origional mastiff blood, or just recent selective breeding? and i think there has been many more generations of undocumented crosses with who knows what to say what blood EXACTLY, that any one dog has. it's my understanding that these dogs have a few hundred years of breeding and only about 60 years of registry/records
