Aggressiveness towards
Other Dogs

The most common thing is that the aggressiveness of a dominant dog is directed towards another dog of the same sex. This problem is also more noticeable in male dogs and it is more frequent in some breeds than in others. The aggressiveness is usually greater if the dominant dog is in his own territory.

Some dogs are socially unadapted, but generally the problems have to do with hormones, or they have developed due to a lack of early and continuous contact with other dogs. This might be difficult to solve and you may need professional help.

One way of solving this is to castrate the male dog when he is still young. This reduces this behavior.

Dominant and aggressive dogs want to fight. A fight is usually announced with aggressive postures and growls. If none of the dogs backs off, there will surely be a fight.

Be careful because when a dog fights, he can bite anything or anyone, even his master, which is why it is better not to intervene.

Fierce Defiance
There are some dogs that are potentially dangerous and aggressive, such as the Pitbull, the Bullterrier, the Rotweiller, etc., and with these breeds you have to be extremely careful when you take them out for a walk as they are always on the lookut for a dog fight.

If your dog is aggressive, you should put a muzzle on him before you take him out.

Visual Contact
You have to intervene as soon as you see that your dog and his potential adversary are looking intently into each other's eyes and are growling. Another sign is that their tails stand on end.

The Tense Leash Syndrome
Although you instinctively try to contain the dog by pulling the leash and wrapping it around your fist to shorten the distance between you and him, this usually worsens the situation. Forcing your dog to back away can increase his aggressiveness. What you must do here is turn your dog's head away so that he can't see the other dog.

The Solution
In a quiet environment, start to practice the call with your dog. Put a long leash or retractable leash on him so that he can come to you when you call him to give him one his favorite toys. Once your dog has been trained to come to you in a quiet place, practice this exercise in an open area, with dogs at a certain distance. Reward your dog for not getting aggressive with the other animal. Every time you practice this, reduce the distance between your dog and the other dog, always rewarding your dog for keeping calm.

Prevention
When you are faced with a possibly aggressive situation, turn your dog's attention away with one of his favorite toys and then order him to "sit". Always reward his good behavior. Get your dog used to the muzzle. The muzzle doesn't let him physically bite and reduces his domination.
