Dog Aggression Training
Living with an aggressive dog is stressful, isolating, and sometimes frightening. You may have stopped having visitors over. Walks have become an ordeal. Maybe you’ve been told your dog is “too far gone” or that rehoming is the only option.
We’ve heard it all before — and we disagree. Bark Busters was originally created to save “untrainable” dogs. At Bark Busters, we’ve worked with thousands of aggressive dogs across Canada, and we firmly believe there is hope for every dog.
Our certified Canine Behaviour Therapists come to your home, identify the root cause of the aggression, and give you the tools to communicate with your dog in a way they understand.
Safety Around Dog Aggression
Did you know that every Bark Busters trainer across Canada is required to pass our “Stand Rite, No Bite” safety program? This certification is updated every few years, to make sure our trainers are adhering to the highest standards of safety, when dealing with serious situations.
This program has been so effective, we have worked with home delivery & utility companies to teach them how to stay safe as well!

What Dog Aggression Looks Like
Aggression isn’t just biting. It’s a spectrum of behaviours that can escalate if left unaddressed:
- Growling, snapping, or lunging at people or other dogs
- Resource guarding — protecting food, toys, beds, or even people
- Territorial aggression — barking, charging, or blocking doorways when someone enters your home
- Leash reactivity — pulling, barking, and lunging on walks
- Fear-based aggression — cowering, then snapping when cornered or overwhelmed
- Dog-on-dog aggression — fighting with other dogs in the household or on walks
- Redirected aggression — lashing out at whoever is closest when overstimulated
If any of these sound familiar, you’re not alone. Aggression is one of the most common reasons dog owners seek professional help — and one of the most treatable when approached correctly.
Why Is My Dog Aggressive?
Aggression is almost never about a “bad dog.” It’s a communication problem. Your dog is trying to tell you something — they’re scared, stressed, over-threshold, or haven’t learned how to cope with a situation. Common underlying causes include:
- Fear or anxiety — the #1 driver of aggression in dogs. A dog that feels threatened will protect itself.
- Lack of guidance — when a dog doesn’t trust that their human is taking care of the situation, they take matters into their own paws.
- Past trauma or under-socialization — rescue dogs, puppy mill dogs, or dogs with limited early-life exposure to people, sounds, or environments.
- Pain or medical issues — a dog in discomfort may snap when touched or approached.
- Learned behaviour — if aggression has “worked” in the past (the threat went away), the dog repeats it.
Our Behaviour Therapists are trained to read your dog’s body language, identify triggers, and determine what’s driving the behaviour — so we treat the cause, not just the symptoms.
How Bark Busters Treats Aggression
We don’t use shock collars, prong collars, physical or punishment-based methods. Our approach is built on communication, trust, and understanding your dog’s psychology.
Step 1 — In-Home Assessment
We come to your home because that’s where the behaviour happens. Your dog is in their natural environment, so we see the real picture — not a stressed-out dog in a sterile clinic. We observe your dog’s body language, review your household dynamics, and listen to your concerns.
Step 2 — Identifying Triggers & Root Causes
Is the aggression fear-based? Territorial? Resource-related? The answer changes the approach entirely. We map out your dog’s triggers and build a customized plan.
Step 3 — Teaching Communication
Using Bark Busters’ proven verbal communication methods, we teach you how to speak to your dog in a way they instinctively understand. Dogs respond to tone, body language, and consistency — not punishment. Most owners see a noticeable shift in their dog’s behaviour within the first session.
Step 4 — Lifetime Support
Aggression doesn’t resolve overnight. That’s why every Bark Busters program includes our Written Lifetime Guarantee — you always have support for the life of your dog, at no additional cost. If you need more help, have a question or a behaviour is tricky, we’re here for you!
Who This Is For

Aggression Training FAQs
Q: Can an aggressive dog really be trained?
Yes. In over 35 years and over a million dogs trained globally, we’ve seen transformation in dogs that other trainers gave up on.
Aggression is a behaviour, not a personality trait — and behaviours can be changed.
Q: Is my dog too old for training?
No. Dogs learn at every age. We’ve successfully worked with senior dogs who’ve had aggression issues for years. It’s never too late.
Q: How many sessions will it take?
Most owners see improvement in the first session. The number of follow-ups depends on the severity and how consistently you practice the techniques at home. With our Lifetime Guarantee, you’re covered for as many sessions as you need.
Q: Do you use punishment or dominance techniques?
Absolutely not. Our methods are non-physical and based on clear verbal communication. We don’t use shock collars, choke chains, alpha rolls, or any aversive tools.
