Chewing is natural for dogs, but they must be taught what items are acceptable and what items are off-limits. When introducing a new puppy or dog to a home, confine them to a small area with chew toys to prevent inappropriate chewing. As the dog gains access to more space, keep unwanted items picked up but praise and reward the dog for chewing toys instead of punishing them for mistakes. Consistent training teaches dogs appropriate chewing behavior for their safety and the owner's property.
