Not to be a jerk, but no. It is typically hereditary, I would say 99.9% of the time. I have seen it in certain lines. And it passes from generation to generation. It is a flaw in a line and should be weeded out. AKC field trials are the basis of what things we want to have in hunting dogs. Set up to simulate a days hunt, under control, on live birds the best we can. And In our rule book it is a flaw that shall be severely punished. I tend to agree. The good is it is very few lines. I know some out there, and those that come from them, and some British lines we see in the states as well. I know one breeder who breeds the heck out of her dogs knowing full well the issue, but does not care. All about money for her. Pup after pup have the same issue. I just shake my head. Now as far as your dog, you can work on it, there is a few tricks. But for a hunting dog there is no real need. I would just enjoy the good things he does and keep hunting. :thumbsup:
