Here's the deal. My 13 week Mal male pup barks throughout OB training except when he is eating his treat or chewing on his tug. Other than the barking, he is doing what I want him to do. My German Shepherd pup never did this. Oh yeah, my Mal's drives are extreme, and I'm sure that contributes to the barking. When building drive, and I'm keeping him busy, he doesn't bark, but get him to come to you and ask him to sit, down, stand, and he starts yiping. Opinions?
