Instructions
Take your dog to an area where to encounter people or other dogs at a distance. Keep your dog on a leash for safety.
Offer your dog a treat once you notice another dog approaching. Continue to give your dog treats to maintain its focus on the treats rather than the strange dog. If the treats do not keep his attention, give him a treat each time he looks at the strange dog. This will help make the sight of another dog a pleasant experience. Provide verbal reassurance such as "Good dog" once the strange dog has completely passed out of view.
Walk your dog with a friend who has an unknown friendly dog. Maintain a close distance to your friend and the other dog as you feed your dog treats. Do not reward your dog for aggressive behavior. Feed the dogs treats together so that they share. If your dog does not show aggression, allow him to explore the other dog's scent.
How to Resocialize a Dog After an Attack
Dog-to-dog aggression is one of the most common behavior problems that owners must deal with. According to Dr. Ian Dunbar, founder of the Association of Pet Dog Trainers, the major reason is that during puppyhood, dogs often are deprived of adequate socialization with other good-natured dogs. Dogs that show aggressiveness usually are kept isolated which increase antisocial behavior. To resocialize a dog after an attack, regular contact with other dogs is necessary.
