out of 4 apbt's i have he's the only one who does this. i beleive its a sign of not being intelligent. Yeah it's cute but only for soooo long. he runs the backyard like the rest of em for at least 4 hours a day. i'll try the "NO" approach and bring him to a sit. i've tried distracting him with other toys, but 5 minutes later he's back at the best toy in the world his TAIL. yeah don't get me wrong it's hilarious after a few beers, but when my grandmother and mother come by he's running into there knees trying to catch the whip on his ass.
