No 1. Fear Aggression
Fear aggression is the most common aggression. By showing fear aggression, your dog is saying “Stay away from me!” You need to take him or her out of the situation immediately.
Also, exposing your dog to a stimulus starting at a low intensity is necessary so that your dog can overcome the fear.
No 2. Pain-related Aggression
Dogs may get aggressive when they are in pain. This type of aggression is not easy to notice.
When your dog is old and suddenly aggressive, go see a vet.
No 3. Defensive Aggression
When dogs play with each other, they do play-biting and growling. These are normal play activities. However, you may find defensive aggression when one feels uncomfortable and gives ‘NO’ signals but the other dog just keeps doing it.
No 4. Possessive Aggression
If your dog is possessive in his toys and you try to take it, your dog will show aggression.
To fix this, you need to figure out what your dog wants to control. Then, have your dog give it up as you provide a better substitute.
No 5. Redirected Aggression
Redirected aggression occurs when your dog is enraged but cannot control or approach it. To prevent this, make sure to keep some distance when you intervene.
No 6. Social Aggression
Social aggression occurs when you and your dog have different needs. You have to reinforce your dog to do what you want your dog to do. For example, throw snacks or toys on the floor if you want your dog to go down from a couch.
Other than these 6 types of aggression, there will be other causes. If you have no idea why your dog shows aggression, consult with a vet or a trainer.
