It helps to know the signs and types of aggression, so you’d be able to know how to calm an aggressive dog.
Types of Dog Aggression
In learning how to deal with an aggressive dog, understand that the behavior may stem from all sorts of reasons. It could come from dog anxiety when a dog is exposed to an unfamiliar person or environment. Aggression could also be due to pain your dog may be suffering from or fear. The following are the different types of aggression you may see in dogs:
· Social aggression
Social aggression may occur when more than one dog is present in the household. A dog may also show aggression when you’re unable to properly socialize your dog.

· Pain-induced aggression
A dog may behave aggressively if he’s in pain due to an injury or a medical condition. This could present you with a very dangerous situation. A dog in pain may bite if you try to touch or help him.
· Fear-motivated aggression
Fearful dogs have a high tendency to behave aggressively. If you want to know how to stop dog aggression towards strangers, you may consider that your dog is acting out of perceived fear.

Aggression in dogs may merely be redirected to you or other people or dogs, but stem from an entirely different stimulus that a dog may be unable to attack directly.

May sound silly, yet when a dog barks “in alarm” (heard unusual noise, someone is approaching the door, etc) I immediately attempt to locate reason of bark, then kindly “thank” the dog…Good Job, I say…reassuring the dog that they did well and warned me…and i have it under control…at that point i focus on letting the dog “off the hook” .. If there is more barking, then the issue has not yet been satisfied as far as the dog is concerned… It’s all about paying attention, praising your dog for doing what he’s supposed to do, then release the dog from responsibility….(i did a lot of reading about dog behavior….watch them…and learn)
My rescue dog was on the street for a time. His leg got broken somehow. He clearly has traces of Cattle Dog & German shepherd. He is lovely and sweet with adults and calm children. He lunges, growls, and barks at other dogs almost always. The vet estimates his age at 6 yrs. From your article I think he has natural predatory aggression, territorial agression, and anxiety. I\'m learning and trying to put safety 100% first.
Carla Martinez, yes my stray dogs are the same they chase vehicles only when it is moving at high speed and can be accidentally or they bark at other dog from different territory but the rarely had any fights
