Does playing tug-of-war cause aggression?

Research indicates that a dog can understand play and not turn suddenly aggressive from a game. If your dog is already possessive of toys, tug-of-war should not be an option. For most dogs, however, tug is a great game, if you play by the rules.

1. You start the game. Ignore your dog if he tries to bully you into playing
2. When you ask for the dog to release the toy, he does so. If he refuses, drop the toy and walk away. Game over.
3. If your dog EVER – even accidentally – puts his teeth on your skin or clothing, the game ends. Drop the toy and walk away, no exceptions.
4. Don’t tug harder than your dog tugs on the toy. With these rules, tug is a safe and fun energy- burning game for both of you.
