How to Stop Excessive Puppy Chewinghttp://www.Dog-Training-Works.com - Puppies chew - that's a fact of life, like gravity, or taxes. This, however, doesn't necessarily make it acceptable, especially when the puppy in question chews up everything in sight. The problem is, unlike children, dogs will not naturally outgrow this habit as they get older. In fact, when left unchecked, chewing can become a habit that's almost impossible to break. If you want to stop excessive puppy chewing, you have to start as early as possible. You have to start NOW.
