There are many reasons that a dog might become aggressive toward other dogs.Some dogs might be fearful around other dogs.In other cases the dog may strive to be the dominant dog.In other situations, the dog may become aggressive since he is defending its territory.  The dog can also be taught to be aggressive by the owner rather than being socialized to the other dogs.Some dogs may also be protective of their owners and thus become aggressive and sometimes become sexually aggressive also.

Tips

One major way to stop dog aggression is to ensure that a dog gets to socialize while it is a puppy to other animals.Puppies should be given the opportunity to play with other dogs that are mature and well behaved.In this way, they learn the right and proper dog behavior from the older animals.  The puppy earns that other dogs are okay and that he does not have to fight to defend the territory or protect the owner from the other animals.

Another way to stop dog aggression when a dog starts to become aggressive is to address the issue immediately each time it happens.  The dog should never be allowed to get away from this type of dangerous behavior.A head collar or muzzle can be very effective while the dog is still in training to stop dog aggression, but its not texactly the solution to the problem.

A way to stop dog aggression is through strict training so that the dog is tuned into the instructions of the owner rather than focusing on the other animal.  The dog should be trained to focus on the owner so that his attention is there and the owner can give another command to the dog, such as ‘down’ or ’sit’ while there is another dog around.  The owner should also teach himself to control his anxious feelings and behavior, as small as it might be, so that the dog does not take a nervous cue from the owner.This can also help to stop dog aggression since the dog always learns from the owner.  Once the dog has been trained to focus, the dog can also be distracted by being trained to look for a treat when there is another dog around.The treat can be thrown to the ground and the dog can be told to find it, thus distracting the dog from other dogs and stop the dog aggression before it starts.
