In addition to specific training, puppies also need to learn how to control their own behaviour and limit potential injury to others. Part of this process involves learning that the use of teeth and nails are not acceptable when interacting with owners and other pets, and it is therefore important not to encourage their use during play. Play should be directed to appropriate toys instead.
The most important thing to focus on is to teach your puppy to be calm and settled. This means rewarding your puppy with quiet praise whenever they are lying quietly.
