Some of the best strike dogs I ever seen wouldn't look at a pig in a pen. I know plenty of people that'll say the same I know Boar Collector has seen some top notch strike dogs that wouldn't look at a hog in a pen. Idk Wat to tell you about the dry runs....
x2...I have seen some very good hog dogs that won't bay in a pen...sometimes I think they were trained in the bay pen too often or too long and the dogs learned to just not bay...but in the woods they are some sure enough hogdogs....
