When you have a destructive dog like little Percy, life can be a matter of following him from chewed table leg, to shredded armchair cushions, and more destroyed items in your home than you can count. It can also make him challenging to groom as he will continually be trying to bite and chew the tools, the toys, the grooming stand, and anything else he can get his teeth on. Of course, you could always try a muzzle, but this a lot like using a band-aid on a cut that needs stitches. Your best shot is to work with Percy until he understands his behavior is not acceptable.
Most dogs develop a destructive tendency because they are bored or because they are still teething and don't have the right things to chew on. Older dogs may also become destructive because their gums are sore, and chewing helps to ease the pain. Once you discover the cause of his destructive behavior, you can start working on finding a way to stop it. In the meantime, here are a couple of grooming methods you can try.
Just because Percy is a little on the destructive side, doesn't mean he shouldn't still be groomed on a weekly basis. Remember, it's more for his good health than his good looks. Keep redirecting his attention each time he starts to lose focus. Given enough time and patience, your pup will eventually get past his destructive behavior and start relaxing and enjoying the weekly sessions.
