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

How much does dog aggression training cost in Sudbury?

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 Lori at 249-979-5674 for a personalized quote.

Is it safe to train an aggressive dog at home?

Lori 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 Lori 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?

Lori 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 Lori Johnston

I’ve transformed hundreds of dogs and families through my unwavering commitment to animal welfare and rescue. As a Behaviour Therapist and Trainer, I bring an invaluable perspective shaped by decades dedicated to helping local rescues. From working with rescue teams to bring dogs in from remote Northern Ontario communities to fostering countless medical rehabilitation cases, I’ve witnessed firsthand the resilience of dogs facing fear, trust issues, and the challenges of having no training. My experience rehabilitating these dogs to full recovery deepened my understanding of what’s truly possible with proper guidance and compassionate care.

After experiencing the transformative power of Bark Busters methods with my own foster dogs, I became a passionate advocate for the system. Recognizing the opportunity to help even more families and rescue dogs, I became determined to share that same life-changing experience with others. As a certified Behaviour Therapist and Trainer, I specialize in helping dogs and their owners communicate in entirely new ways, creating the harmonious, happy relationships that every family deserves.

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

Becoming a trainer has given me an opportunity to work with dogs and to be a positive influence in helping dogs and their owners succeed in a more harmonious, happy way. Teaching owners how to communicate with their dog in a whole new way is the best! I love watching them both succeed and learn.

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.

Sudbury Families Who Overcame Dog Aggression With Lori

“We highly recommend Lori Johnston at BarkBusters! Lori is incredibly knowledgeable and confident, which was evident from our very first session. We have an active Border Collie/Sheltie cross named Chloe, and Lori provided us with specific exercises that have been fantastic to work on. Chloe is responding well to the training. One of the best parts of working with Lori is her flexibility. She provides in-home training but is also available electronically. We really appreciate the fact that she is always just a phone call or text away if we have questions.
While we still feel we have more work to do with Chloe, we are so thankful to have Lori available to help us through the process. If you are looking for an effective and accessible trainer, Lori is the best!”

— David Kilgour, Sudbury

“We couldn’t be happier with our Bark Busters trainer, Lori. She is incredibly kind, approachable, and absolutely amazing with our dog, Sullie. From day one, she made us feel comfortable and confident, and it’s so clear that she truly knows what she’s doing. Lori is extremely knowledgeable, patient, and genuinely cares about both the dog and the owners. She’s also been fantastic at accommodating our schedules, which has made the whole experience even better and stress-free. We honestly wouldn’t want it any other way — we’re so grateful to have Lori helping us raise Sullie the right way!”

— Megan Faggioni, Sudbury

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 Sudbury 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 Sudbury & North Bay, Surrey, Delta, New Westminster, Langley, East Sudbury, Kitsilano, Shaughnessy, Ladner, Tsawwassen, White Rock, Abbotsford, and surrounding Lower Mainland areas.
