I was having some issues with a very high drive pup I got this winter. The problems were mostly ME not excercising the pup enough. He was unlike any of the terriers, other running dog breeds, collies, pits etc that I had ever had. Once I was walking him and playing with him for at LEAST an hour in the morning and a couple in the evening, the problems virtually stopped. It is not enough to be WITH the dog, you have to be active with it, teach it basic obedience, little tricks, they WANT to learn at that age. So if it can't go out because of it's jabs, put it on a leash and walk patterns in
