bill hines used to sell registered catahoula bulls. he ran and ad for em in either feathered warrior or grit and steele. a friend of mine had a ab and cat from an accidental breeding and the result was a big brindle bulldog lookin dog that most times was straight turn in bulldog but at times he would remember who his mama was and just go to straight bayin.
Scott and I have a Hines video with those advertised on it. It was the copy he made for Rayburn.
