Cuatro Hindes is the son of "Little" Roy Hindes & grandson of "Big" Roy Hindes - they have a ranch that's been under high fence since the 70's south of Charlotte. It's an amazing place to check out. (Check Texas Trophy Hunters - they usually have a featured buck killed on the Hindes Ranch)
Anyway, Big Roy (rest in peace)raised some legendary deer tracking dogs & Little Roy & Cuatro have continued the tradition. If a trophy buck is lost in South Texas, they usually get the call to find it.
"Jethro" was the name of their best dog, but I think he's been recently retired. He was legendary in South Texas. I imagine Cuatro is capitalizing on the ability in Jethro's bloodline & is selling pups.
