haha yea, tippy (the mix) doesnt chew much anymore but when he was a puppy he literally chewed a hole in the wall! it was a flat wall, we dunno how the hell he did it, it it was a hole you could put your fist in! hank (the pit) will chew anything you give him. he loves soda cans and bottles, whats funny is he plays with his old plastic dish and when it flips over and he cant flip it right side up he gets pissed and starts barking at it
