The key to stopping destructive behavior is to identify the cause. Teething, separation anxiety, attention seeking behavior and boredom can each result in chewing or digging. Often a dog that is bored or lacks sufficient exercise will exhibit destructive behavior. Regardless of the cause, the first course of action with every dog is to offer plenty of play and exercise time and basic obedience training to create discipline and affection. Physical and mental exercise alone can work wonders for many destructive pets.
