Mike I had two Byrne dogs back about 15 years ago. Never did make dogs. One died at 11 months old and the other did not make it after a lot of hunting. There is good ones hunted with one. I had my own stock a long time ago.
I had good luck going to bird dog breaders that had bird dogs that would not stand for a covey that would flush and get them and hunt them. I may try that. I called the person about the boykins and never got a reply back.
We will find one It will happen.
