Haha if chewing on metal makes them a good working candidate, my boy must be a champion! He completely chewed through the metal car barrier that kept him in the back of my truck [as well as eating the entire interior of three trucks now] chewed through a chain link dog kennel, and has chewed up multiple metal dog bowls. And with his pure strength he has broken two heavy duty wire cables, two leather collars, a choke chain and a prong collar. Have fun with your little monster!!
