- 1). Understand the several types of dog aggression. Dogs can show aggression as a means of protecting their territory or possessions, to show dominance, if they are afraid or because a natural aggression--toward an intruder or a potential source of food--is displaced and redirected toward something else. For example, two dogs stuck behind a fence who see someone breaking into a house may attack each other, as they cannot attack the intruder.
- 2). Take your dog to the veterinarian. Dogs can also become aggressive due to illness, so you want to have the vet make sure your dog is healthy.
- 3). Have your aggressive dog spayed or neutered. Dogs that are intact are more likely to display dominance aggression.
- 4). Supervise your aggressive dog at all times. Your top priority is to keep people around the dog safe. Place a muzzle over your dog's mouth to keep it from biting. If the dog reacts poorly to strangers, keep him confined in a room away from them. Limit your pooch's contact with people and unfamiliar settings if these set him off.
- 5). Keep your territorial-aggressive dog away from treats or toys. If your dog has a favorite bone that he guards and that causes him to snap at anybody who comes near, take it away and do not allow him access to any similar toys and treats until his behavior has been modified.
- 6). Consult a dog trainer. Like people, each dog is different, and has different triggers for his aggressive behaviors. A specialist can help you understand the root of your dog's aggressive behavior and remedy it if the aforementioned steps do not prove sufficient.
