Alice Texas and a leopard cur question

A. E. Outlaw, my Great Uncle lived at Moore, TX and had 10-15 lep/cat dogs that he used for working and catching wild cattle. I am not sure of the gentleman at Alice of who you speak but do remember a few of Mr. Outlaws dogs that had the longer, rougher hair coats. I can't remember where the dogs came from, but I am guessing somewhere in South Texas as the only dogs I remember purchasing from anywhere else came from Mississippi. This would have been from the late '50s up through the '70s.
Mr. Outlaw was known to have the best cow dogs for catching wild cattle of anyone in that country. They were really gritty and had pretty good noses as I can remember going with Uncle Everett (A. E.) and getting paid by the head for penning wild cattle. We would ride into a big pasture on the downwind side and the dogs would scatter trying to pick up the trail or wind the cattle. Many times, we would start them at a stock tank and the dogs would trail up and bay the brahman crosses that were about as wild as the deer. Once they got the cattle stopped and bayed up, we would move in and drive them to corrals or rope them if we could get a trailer fairly close. Brush was extremely thick so most times, tried to push to pens.
One of his sons, Don Outlaw tried to keep these dogs but he is up in age and no longer cowboying. I doubt that there are any of them left.
Adios,
Gary
