Aggression between household dogs can be difficult to treat.

Most puppies and many adolescent dogs love to explore and chew, so it should be no surprise when they steal household objects. When you try to get these items back from your dog, a chase ensues because the game is fun, because the dog enjoys the attention and because the dog is reluctant to give up its new found treasure.

If your dog has threatened or displayed any signs of aggression, the problem is likely to continue until appropriate steps can be taken to identify the cause and modify the pet's behavior. A necessary first step is prevention and avoidance of further incidents. Not only is this essential to ensure safety, but each aggressive display may actually serve to increase the chances that the aggressive behavior will continue.

Even though dogs are a social species, some dogs exhibit aggression toward dogs outside their immediate social circle. There are many possible reasons for the behavior, and an accurate assessment is essential. A medical exam is important to check for underlying pain or illness. Treatment can be effective once the causes for the behavior have been determined.

Treatment for aggression toward unfamiliar dogs is available, and the outcome can be positive. An accurate medical and behavioral assessment is needed as treatment plans are designed based on the context and underlying motivation for the behavior. To start, management is used to prevent aggressive encounters. Behavior modification is always needed and may include desensitization, counterconditioning, and response substitution. Medication is sometimes used to lower anxiety and frustration.

Dogs that rush to the door, barking, can frighten visitors. An excited dog could rush out the door and be injured. Barking and rushing toward the door can be managed by teaching dogs an appropriate alternative behavior. Some dogs can become very aroused at the door and can exhibit aggressive behavior. Professional guidance may be needed.
