Meet Horacio D’Argence

I’ve transformed hundreds of dogs and their families across Calgary and beyond. With deep expertise in canine behaviour and a genuine passion for helping families, I’m proud to be one of the region’s most trusted dog behaviourists in Calgary.

Dog aggression is one of the most stressful behaviour problems a family can face – and one of the most misunderstood. Many owners are told their aggressive dog can’t be helped, or that punishment is the answer. Neither is true. Growing up on my family’s working ranch in southern Mexico, surrounded by horses, cattle, and dogs, I developed an innate understanding of animal behaviour and the bond between humans and animals.

As a certified Behaviour Therapist, I specialize in dog-to-dog aggression, aggression toward people, resource guarding, territorial behaviour, and leash reactivity. Every case starts with understanding why your dog is aggressive – fear, frustration, pain, or poor communication – and then teaching you the techniques to change it.

Training happens in your home, where the aggression actually occurs. No group classes, no stressful car rides. Just real results in the environment that matters most. Most families see a visible change during the first 2 to 2.5 hour session.

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.

Calgary Families Who Overcame Dog Aggression With Horacio

“We learned so much from Horacio, and we are working hard to put his training into action. We saw an immediate improvement and were incredulous at the simplicity of a few behaviours that WE needed to change. We are very grateful for Horacio and Bark Busters!!! Thank you, thank you, thank you!”

—Laurie W., Calgary

“Having Horatio come to our home to work with our family (humans and dogs) was the best fit for us. Horatio helped us reach a deeper understanding of our dogs and how to communicate with them effectively. The lifetime commitment Bark Busters provides is so reassuring, knowing we will always have someone to turn to if we need or want further support. Within a day of our first lesson, after the initial overwhelm of all the info, we started to see changes as we implemented the recommended strategies. It’s one week late,r and we are so happy! Less stress, more control, and more relaxed dogs. Looking forward to our next lessons. Thanks, Horatio!”

— Zaina Besaw, Calgary

FAQs

How much does training cost?

We offer a one-time fee that includes your initial assessment, 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. 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 behaviours 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. Your trainer will assess and advise you on what your specific dog will need. You do not need to buy anything in advance.

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. The follow-up sessions are typically an hour.

What areas do you serve?

Horacio offers dog training services in Calgary, Sundance, Airdrie, Chestermere, Crossfield, Strathmore, Okotoks, High River, and De Winton. But we have trainers attending other regions
