Why You Shouldn't Wait

Aggression Escalates

A dog that growled at strangers six months ago and now lunges is not going through a phase. Every rehearsal of the aggressive response makes it more likely to happen again and more severe each time.

Liability Grows

A bite incident can result in $5,000–$50,000+ in liability. Many homeowner insurance policies exclude or cancel for dogs with a documented bite history. Intervention before a bite is dramatically less costly than after.

DIY Methods Make It Worse

Punishment applied to an already anxious or fearful dog frequently escalates aggression. Without understanding the trigger and type of aggression, self-directed training often addresses the symptom and worsens the cause.

How We Address Aggression

Not all aggression looks the same. Fear-based aggression, resource guarding, leash frustration, and inter-dog conflict each require a different approach. Our process:

  1. 1

    Free Evaluation

    We meet your dog, observe behavior, and identify the type of aggression and its triggers. This is a professional assessment — not a sales call.

  2. 2

    Customized Modification Plan

    We build a plan specific to your dog's triggers, history, and severity. No two aggressive dogs are handled identically.

  3. 3

    Day Train Program

    Your dog trains at our Valhalla facility one full day per week for 5 weeks. Controlled trigger exposure builds new behavioral responses systematically.

  4. 4

    Owner Coaching

    You learn to read your dog's signals, handle them safely, and reinforce calm behavior at home. Training that only changes the dog — not the owner — regresses.

  5. 5

    Lifetime Group Classes

    Ongoing reinforcement through our structured group class environment, included for life. This prevents the maintenance dropout that causes relapse.

Frequently Asked Questions

Can aggressive dog behavior be fixed with training?

Yes. Most aggression cases respond well to structured professional intervention when addressed early and committed to fully. Our certified trainers identify the root trigger — fear, resource guarding, leash frustration, or conflict aggression — and build a customized modification plan.

How long does aggressive dog training take?

Most aggressive dogs show meaningful improvement within 8–12 weeks of our Day Train program. Timeline depends on severity, trigger specificity, and owner consistency during the process.

Do you work with dogs that have bitten someone?

Yes. We work with dogs that have a bite history. It requires a professional assessment, a structured protocol, and controlled exposure work — none of which can be replicated by group classes or DIY training.
