What you get

How the program actually works.

01

Safety first, always

A clear management plan for the household before any training pressure goes on the dog. You stay safe while we do the work.

02

Root cause over symptom

We address the trigger, the emotion underneath, and the dog's default response. Not just suppress the surface behavior.

03

Owner-operated communication

Even the hardest dog needs a clear "yes, no, good." That language is what gives an aggression case somewhere to go.

04

Honest about the runway

Real aggression work takes time. We will tell you the truth about what is realistic before you spend the money.

Pricing

Scoped on the consultation.

Free
Consultation, no pressure We do not quote behavior or aggression cases blind. The right number depends on the dog, the household, and the work, so we scope it on the free consultation.

My Presa Canario had developed aggressive tendencies, and I was really struggling to control her. After just four weeks of their dedicated training program, my dog has transformed. The trainers at HighCaliber are exceptionally knowledgeable, patient, and genuinely care about the well-being of the dogs they work with. Now, she is incredibly obedient, calm, and reliable, even around other people and animals.

02

The program runs

Six days a week, two sessions a day. Andrew runs every session personally. Engagement work, engagement, then proofed obedience.

03

The handover

You get private follow-up sessions, three on the 4-week, six on the 8-week, so the new behaviors stick at home.

Common Questions

Things owners ask

My dog has bitten before. Will you take us?

Yes, that is exactly the kind of case we handle. We will ask about bite history on the consultation so we can plan the right intake.

What tools do you use?

We are a balanced training program. The tool is matched to the dog, the behavior, and the goal, properly conditioned, never as a shortcut. We will walk you through what we use and why before any of it touches your dog.

How long does aggression work take?

Longer than basic obedience, typically several weeks of structured work and ongoing maintenance. Lasting results require the time. We will give you a real estimate on the consultation.

I have already tried other trainers and nothing held.

That is most of the dogs we see in this category. Bring us the history, including what was tried, what worked for a minute, and what fell apart. We work from there.
