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

How much does dog aggression training cost in York Region?

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 Kyli at 289-231-8675 for a personalized quote.

Is it safe to train an aggressive dog at home?

Kyli 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 Kyli 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?

Kyli 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 Kyli Horton

I’ve transformed hundreds of dogs and families through my unwavering commitment to animal welfare and behaviour. As a Behaviour Therapist and Trainer, I bring invaluable expertise shaped by years of working in the animal care industry. From my experience as a kennel attendant at a veterinary clinic to my work as an animal behaviourist with Animal Services in Alberta, and several years in the pet food industry, I’ve developed a comprehensive understanding of canine needs and behaviour. My background in animal care provides the foundation for my passionate advocacy on behalf of dogs facing behavioural challenges.

During my time with Animal Services, I witnessed firsthand how many dogs lost their lives due to behavioural issues that were completely fixable with proper guidance and support. Those sobering experiences became my catalyst for change. Determined to prevent unnecessary loss and help families build better relationships with their dogs, I joined Bark Busters to educate and empower dog owners with practical, effective training methods. As a certified Behaviour Therapist and Trainer, I specialise in helping families understand their dogs’ behaviour and implement lasting change, ensuring that dogs and their owners can enjoy long, happy lives together.

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

My mission with Bark Busters is to educate and empower dog owners with practical, effective training methods that lead to lasting behaviour change and stronger bonds, so families and their dogs can enjoy a long, happy life together.

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.

York Region Families Who Overcame Dog Aggression With Kyli

“In the first meeting, we learned more about our individual dog, ways to communicate with her and how she is communicating with us. We are so impressed with our dog’s responses and aptitude…”

— Mirja Raita, Newmarket

“Today was a huge accomplishment. I had flowers delivered for my birthday and usually I would not be able to open the door because of the dogs jumping all over it barking. Today they both sat in the living room close to foyer, with their eyes on the doorway, but did not move until the transaction was completed.”

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 York Region 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.
