I’ve grown up surrounded by animals – dogs, cats, cows, goats, sheep, and horses and that has shaped me into what I am today – a crazy cat lady who always has a place for one more cat (or a dog). I’ve got two female cats – Kitty and Roni, and two tomcats – Blacky and Shaggy, but I also feed my neighbors’ cats when they come for a visit. I just can’t say no to them.

Common dog aggression triggers

Are you wondering about dog aggression triggers? If your dog is acting aggressively or protectively, read on for 7 things that could be setting him off!

Despite what some people think, dogs are rarely aggressive without reason.

Often it’s the lack of proper socialization while young that creates suspicious and untrusting dogs.

But it might even be a medical condition or past abuse.

The triggers I’m going to talk about are general ones to give you an idea of what to look for when analyzing why your dog has acted aggressively.

#1 Children and small animals

Unfortunately, not all dog breeds are child-friendly or pet-friendly.

Some lack the patience required to tolerate the curiosity of a small child, while others have a strong prey drive.

In addition to this, children and small animals make erratic and sudden movements.

That’s bad for two reasons:

  • The dog might get afraid by the sudden movement and react defensively.
  • Natural chasing instinct might kick in.

Besides, children sometimes might hurt a dog by accident. In turn, the dog might bite to defend itself. That’s why you should never leave a child alone with a dog without adult supervision.

#2 Fast-moving objects

I remember Lucky. He was a good dog, but the poor thing could control himself around bikes.

Every time a biker would pass near us, I had to keep a firm grasp on the leash. Otherwise, the biker would have gone home without pants or shoes.

That’s a common problem because dogs are natural predators and fast moving object awake their predator’s instinct.

In addition to this, dogs might get so excited when watching a moving object that they have to attack.

So, you have to be careful around:

  • Small animals like squirrels and cats
  • Bikes
  • Joggers/runners
  • Skateboards
  • Motor vehicles

#3 Other dogs

You might think that dogs get on well with each other. Think again!

While some dog breeds love the company of a fellow canine, others are dog-aggressive.

They see other dogs as a threat to their territory and authority. As a result, they need to pick a fight and establish the pecking order.

If you’re thinking about adopting a second dog, most specialists advise that you get a dog of the opposite gender to avoid dog-on-dog aggression.

#4 Getting too close for the dog’s liking

The one rule I remember about dogs from my childhood is, “Never startled a dog.”

Even the mellowest dog won’t react well if you invade his comfort zone without warning.

Far worse would be to startle Fido while he is sleeping or absorbed in other activities.

In addition to this, nervous or anxious dogs might think that you represent a threat when you move suddenly in their direction. Logically, they will get aggressive as a defense mechanism.

#5 Being handled in certain ways

Another dog aggression trigger is handling the dog in a way that Fido doesn’t like.

For example, trimming nails, brushing coat, bathing, medical procedures, and so on.

While some of these are necessary for the well-being of your dog, you should proceed carefully if such actions trigger aggression.

Furthermore, some dogs don’t like to be petted or being picked up. Respect this wish. Otherwise, it will be hard to establish a trust bond between you and your dog.

#6 Frustration and pain

A dog that can’t reach the object of its frustration because of a gate or a leash might redirect his aggression to a nearby object.

That’s why when you see that your dog is getting agitated and frustrated by another dog, animal, or person you should intervene as soon as possible:

  • Block the view from your window or yard so that the dog won’t be irritated by animals and people
  • Move in the opposite direction if you’re on the street.
  • Put a physical barrier between the dog and the thing that frustrates him.

In addition to frustration, pain also makes a dog react aggressively. So, any sudden change in your dog’s demeanor should be evaluated by a vet.

#7 Resource guarding

One of the most common reasons why a dog gets aggressive is to protect its food, sleeping place, toys, etc.

That’s why Fido might bark, growl, and show teeth if he thinks that you or another dog are going to take something from him. That’s called resource guarding.

Territory aggression is also a form of resource guarding.

The dog considers the whole family and the house as valuable objects that should be protected no matter what. So, when a strange animal/person appears, your pooch might react aggressively to defend you.

Once you know your dog’s triggers, you can do your best to avoid them or work on your dog’s reaction towards them.
