Waylon why I ask if you haave even owned any as I suspect you haven't you would see how some coyote could be in there by the way they act. I cull pretty hard for disobedience and the damn lacys can be some wiley suckers. There is no documentation from the lacy brothers them selves that I am aware of other than some saying them driving hogs with lacys the only documentation I have seen is from kin folk of the lacy brothers.
I've had some leopard dogs that you can't put your hands on and just have that look in their eyes. So, does this mean they have yote/wolf blood in them? You can't pick out one trait and say they must have some yote in em because of it!
