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 Kitchener-Waterloo has helped hundreds of families resolve aggression issues using non-punitive, communication-based methods.

How much does dog aggression training cost in Kitchener-Waterloo?

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 Tim at 519-993-2908 for a personalized quote.

Is it safe to train an aggressive dog at home?

Tim 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 Tim 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?

Tim 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.

Tim Girouard Bark Busters dog trainer Kitchener Waterloo

✔ Behaviour Therapist

Meet Tim Girouard

Over more than 18 years, I’ve transformed almost 4,000 dogs and families across my service area. As a Behaviour Therapist and Trainer, I’m proud to be one of the most experienced and trusted dog trainers in my region. Coming from a background in building supplies sales, where I helped people transform their homes, I recognized that the same principles of guidance and support could help families transform their relationships with their dogs.

Over three decades, my wife and I have welcomed eleven rescue dogs into our lives, each one enriching our family in unique ways and deepening my understanding of the profound bond between humans and canines.

After years of working for a large corporation, I became determined to make a real difference by combining my absolute love of dogs with my passion for helping people succeed. I specialize in resolving troubled owner-dog relationships and teaching families the skills they need so behavioural improvements last. As a certified Behaviour Therapist and Trainer, I focus on helping dogs find their place within the family, creating the happiness and harmony that well-behaved companions bring to everyday life.

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

Pets enrich our lives by loving us unconditionally. They give us another reason to get up in the morning and are good for our health. Nothing brings me more joy than seeing a troubled owner-dog relationship resolved and both parties happy and excited about living the rest of their lives together. I’m here to provide the support and guidance they need, every step of the way.

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.

Kitchener-Waterloo Families Who Overcame Dog Aggression With Tim

“Before Tim came to our house, I was ready to give up on the dog, as much as I hated to. He was too strong, too loud, and just had us going crazy. If it wasn’t for the help that we got from Bark Busters, Tim…we would have given up on an amazing dog. I can’t tell you how much of a difference it is now. We learned how to communicate better with Jack (our dog), and also learned that we had a lot to learn. I am so happy with the progress we are making, and it wouldn’t have happened if it were not for you. Thank you so much.”

— Debbie K., Kitchener

“I just wanted to tell all what an outstanding trainer Tim is. We had him out today, and we were amazed at how quickly he was able to make a difference in our dogs’ behaviour. His patience, expertise, and approach really helped us understand our dogs’ mindsets and how to interact with them more effectively. It’s clear that Tim represents Barkbusters exceptionally well, and we’re already seeing improvements thanks to his guidance.”

— Nick Chrzanowski, Kitchener

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. Contact us on the form above for an accurate quote.

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 Kitchener-Waterloo 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 Kitchener, Waterloo & Guelph, Surrey, Delta, New Westminster, Langley, East Kitchener-Waterloo, Kitsilano, Shaughnessy, Ladner, Tsawwassen, White Rock, Abbotsford, and surrounding Lower Mainland areas.
