Can dog aggression be fixed with training?

Yes. Most dog aggression is rooted in fear, anxiety, or poor communication. With the right in-home training approach, aggressive behaviours can be significantly reduced or eliminated. Bark Busters Mississauga has helped hundreds of families resolve aggression issues using non-punitive, communication-based methods.

How much does dog aggression training cost in Mississauga?

Bark Busters offers comprehensive programs rather than per-session pricing. Your program includes the initial consultation, follow-up sessions, and a Written Lifetime Guarantee, so you get ongoing support for the life of your dog. Contact Wil at 778-653-6951 for a personalized quote.

Is it safe to train an aggressive dog at home?

Wil is a certified Behaviour Therapist trained to work safely with aggressive dogs in home environments. Each Bark Busters trainer must pass the Stand Rite No Bite system test. In-home training is actually safer than group settings because it removes the triggers and distractions that escalate aggression.

How quickly will I see results with aggression training?

Most families notice a visible change in their dog's behaviour during the first 2 to 2.5 hour session. Aggression that has built up over years may require multiple sessions, but the communication techniques you learn start working immediately.

My dog is only aggressive on walks. Do you still train at home?

Yes. Leash reactivity and on-walk aggression are among the most common issues Wil addresses. Training starts at home to establish communication, then moves outside to address the specific walk-related triggers your dog reacts to.

Do you use shock collars or muzzles for aggressive dogs?

No. We do not use any form of shock collar, prong collar, or punishment-based tools. Punishing an aggressive dog makes the problem worse. Bark Busters uses communication-based methods that teach your dog to look to you for guidance instead of reacting out of fear.

What types of aggression do you treat?

Wil works with all forms of dog aggression including dog-to-dog aggression, aggression toward people, resource guarding, food aggression, territorial aggression, leash reactivity, and fear-based aggression.

Meet Wil Lawson

Since 2008, I’ve transformed over 3,500 dogs and families across my service area. As a Grand Master Trainer and Behaviour Therapist, I’m proud to be one of the most experienced and trusted dog trainers in my region. With a deep understanding of canine communication and behaviour, I recognized early that dogs and people often struggle to understand each other, and I made the commitment to bridge that gap.

After years of observing how daily interactions shape the trust and respect between dogs and their families, I became determined to help both thrive together. I specialize in increasing mutual trust and respect while helping dogs feel safe in their everyday environments. As a certified Behaviour Therapist and Trainer, I focus on balancing each dog’s unique personality with the family’s needs, ensuring every solution is tailored to create lasting harmony in the home.

My mission is simple: help dog owners understand their canine companions so they can enjoy relaxed, happy dogs.

Witnessing clients become empowered and self-sufficient through our teachings and tools is incredible. You can literally see the stress evaporate for both the dogs and their humans. It’s an amazing privilege to be in a position to help people achieve their goals for their dog.

Did you know that each Bark Busters trainer & certified behaviour therapist is required to pass an aggressive dog safety program that keeps hundreds of trainers safe worldwide. All trainers are required to understand different types of dog aggression, fear and trauma, and know how to approach each situation calmly and safely. You are always in good hands with Bark Busters!

We Understand How Scary
Dog Aggression Can Be

You love your dog, but their aggression is affecting your entire family:

You’re afraid your dog might bite a visitor, a child, or another dog
Walks have become impossible – your dog lunges, barks, and pulls toward every dog or person
You can’t have guests over because your dog growls, snaps, or shows teeth
Mealtimes are tense because your dog guards food bowls, toys, or sleeping spots
You’ve been told your dog is “too aggressive” for group classes or daycare

You’re not alone. Aggression is treatable – and we can help.

Why Our Approach Works Where Others Fail:

In-home training addresses aggression where it actually happens
No punishment, no physical force – this makes aggression worse
Communication-based techniques that create lasting change

You learn to read and redirect your dog’s triggers
Visible improvement often in the first 2-2.5 hour session
Lifetime Support Guarantee – you always have the help you need from Bark Busters.

Mississauga Families Who Overcame Dog Aggression With Wil

“Our experience with Wil has been nothing short of delightful. He has helped us learn how to interact with our dog, leading to a relationship that I have long wanted but have been unable to establish because of his exuberance. Wil’s patience in navigating challenging situations is much appreciated, as is his sense of humour!”

— Lynn Anstead, Mississauga

“We can’t say enough good things about Bark Busters and specifically Wil. We started with Wil just over three weeks ago, and the difference in our girls is astonishing. Wil has supported us from day one and communicates with us regularly if we have concerns or need guidance. From his initial phone conversation to his house visit and check-ins, Wil has been amazing. His communication, education, and guidance are always thoughtful, kind, and clear, and we LOVE working with him. We recommend him to anyone who needs help. Thank you so much, Wil!!”

— Laura Thompson, Mississauga

Dog Aggression Training FAQs

How much does training cost?

We offer a one-time fee that includes your initial assessment, dog training sessions, and lifetime support. Pricing depends on your specific needs. Call 604-484-1941 for a free quote, or book a consultation to discuss your situation.

How quickly will I see results?

Most clients see noticeable improvement during the first session. As Mabel shared, “I’ve never seen Comet so calm and well behaved” after just one session. Long term habits take consistency, don’t forget! We schedule follow up appointments to suit your dog’s needs, and help you! Your lifetime guarantee means you always have the support you need.

Do you train all breeds and ages?

Yes! We’ve successfully trained puppies to senior dogs and all breeds. No dog is too old or too stubborn to learn.

What if my dog is aggressive? Is training safe?

Aggression is one of our specialties. Each Bark Busters trainer is trained on our unique “Stand Rite No Bite” system, and must pass a test to make sure they know how to safely approach aggressive situations. We use safe, effective communication techniques, and coach the humans on how to address the root cause of aggression to create lasting change.

Why in-home training instead of group classes?

Dogs behave differently at home, where they’re most comfortable and where problems actually occur. In-home training addresses the exact behaviors causing you stress, in the exact setting where they happen.

What does "lifetime support" really mean?

You can call us anytime – weeks, months, or years later – for advice or follow-up sessions. There’s no time limit. We’re here for the life of your dog.

Do I need special equipment like bark collars?

We do not use any form of shock collar during aggressive dog training. The Bark Busters Mississauga dog trainer will assess and advise you on what your specific dog will need. You do not need to go buy anything ahead of time.

How long are training sessions?

The initial session is typically 2-2.5 hours. This gives us time to assess your dog, teach you effective techniques, and start seeing results immediately. Follow-up sessions are typically an hour.

What areas do you serve?

We serve Mississauga, Burlington & Oakville, Surrey, Delta, New Westminster, Langley, East Mississauga, Kitsilano, Shaughnessy, Ladner, Tsawwassen, White Rock, Abbotsford, and surrounding Lower Mainland areas.
