I have a Australian shep/border collie/ healer mix that seems to have a mouth fetish. When he's by himself he entertains himself with his toys and he is also kennel trained, so he usually puts himself in his kennel until we get home. However, when we get home he turns into something different. We play with him, exercise him, feed him, and everything. Even after all of this he will grab anything he can and chew it while in our presence. We've tried bitters, muzzles, the tsst, whistle, we've also associated hot sauce in his mouth after we catch him. I just don't get it. we play with him over 6 hours a day and still he chews. Please any suggestions would be great!!!!
