my 8 year old male, Kenny, chews the life out of toys. He does not chew anything else but he destroys the toys. My female also is an obsessive chewer but not as destructive. We get them kongs, cuzs, but they like the puppy chewers like the keys or something that they can carry around. They dont like the nyla bones...does anyone have toy suggestions? no stuffed toys, they shred those, no squeakers, they get the squeaker out then its over...
