What Is Defensive Aggression in Dogs?

Defensive means to defend oneself, while aggression means showing hostile or violent behavior towards something or someone. Everyone has the capability of defensive aggression in them, and that includes your dog. When faced with a threat, humans do one of three things: flee, freeze, or fight. Your dog is no different in that department.

Defensive dog aggression features all three of those terms. If your dog shows any of these three reactions to something, he’s scared. In most cases, pet parents ignore the flee or freeze part of this because they don’t know any better. They do step in when their dog reaches the fight part of the trio because that’s something concrete that needs to be stopped.

However, defensive aggression in dogs can be dangerous and needs to be stopped before a person or pet ends up injured or worse.

What Are the Causes of Aggression in Dogs?

There are a few different causes of aggression in dogs. It’s important to note that it’s very rare for a dog to just become violent and attack a person or another animal out of nowhere. In fact, in most cases, the cause for the aggression in the dog is poor socialization and training. For your pup to be comfortable and unafraid around other animals and humans, they need to be socialized and trained as puppies.

Defensive aggression is actually the most common form of aggression in dogs. If your dog feels threatened by someone or something, they’ll try to flee, then if that doesn’t work, they’ll freeze to get ready to fight. Once the fight response of their fear kicks in, they’ll attack whatever they’re afraid of.

Here are other causes of any type of aggression in dogs:

Pet behaviors can be caused by all kinds of things, but sometimes the source is medical. You can manage veterinary costs with the help of a pet insurance company like Lemonade, which offers adjustable plans and balanced coverage.

What Are the Signs of Defensive Aggression in Dogs?

There are a few signs to watch out for if you think your dog is defensively aggressive. Usually, with this type of aggression, the first signs are subtle. They start with cowering and tucking their tails under their legs, then turning their heads away to let the threat know they want to be left alone. If the human or pet they perceive as a threat doesn’t acknowledge these subtle warnings, the scared dog might bite them or attack.

How to Manage Defensive Aggression in Dogs?

Defensive aggression in dogs can end up being dangerous if it isn’t corrected. The last thing you want is for your pet to bite someone or have to step into the middle of a dog fight. In this section, we’ll discuss how to manage the aggression in your pet before it goes too far.

Listen to Your Pet and Be Their Voice

The best way to prevent and treat defensive aggression in your pet is to listen to your pet and be their voice. If another dog approaches you on one of your walks and stresses your dog, then walk away from the dog he considers a threat.

If a strange person tries to pet your dog and you see your dog turn away, support your dog’s decision and ask the person not to pet them. Never force your dog to meet someone or be petted by someone they don’t seem to like.

When your dog is playing with other dogs, keep an eye on them to ensure they’re not being bullied. If you’re in doubt, it’s best to just end the play session to be on the safe side.

Practicing Body Handling and Restraint at Home Can Help as Well

If you see that your dog’s defensive aggression is getting worse despite your attempts to manage it, it’s best to contact your vet for help. Your vet can help you find the cause for the aggression and get you to a trainer or dog behaviorist who will provide you with the help you need. Never just ignore any type of aggression in your pet. Ignoring it will only make it worse and could end badly for you and your pet.

Never ignore the problem thinking it’ll go away, because it won’t. Any type of aggression, even defensive aggression in dogs, can be dangerous for you, your family, strangers, and the dog itself.
