My boy Derris has one in East Texas off some of my dogs. Goes back to pure performance blood taken to hines/stout blood. He's young but catching on his own in the woods. Once he's got some more time under his belt we will taken him to one of his half sisters.
This ain't him in the pic but it is his pedigree. In the pedigree pic is his sister.

As you can see not only is he working and catching hogs for derris but he's also a great family pet. Catching hogs then little kids hanging off your neck. Gotta love it. Derris tells me nothing but good things coming from this boy. I'm proud he worked out great for him and this outcross we did to this blood was an experiment that so far has produce some good outcross blood for my program.
