  • Utilizes counter-conditioning & desensitization to replace fear responses.

  • Teaches impulse control & emotional regulation under pressure.

  • Includes owner education & support to ensure long-term success.

Who This Program Is For?

Is This The Right Training for Your Dog?

In my expereince, 90% of people who think they have an aggresive dog, actually don't. They are misreading the dog's behavior, needs, and anxieties. This program is for dogs that often need muzzles, have had severe trauma and are at risk for being put down. 

  • ✅ If your dog has bite or injured someone.

  • ✅ If you feel like you're out of options.

  • ✅ Leash reactivity & barrier frustration.

  • ✅ Fear-based aggression toward people or dogs.

  • ✅ Resource guarding & territorial behavior.

  • ✅ Severe anxiety & stress responses.

  • ✅ Dogs who have failed traditional training or been turned away by other trainers.

Aggression is a behavior, not a personality trait. With the right approach, significant improvements can be made and we can help them live a happy life.

2

Aggressive Training Graduate, Brutus

Brutus- The Cane Corsoe

8 Week Aggressive Rehabilitation 

Brutus, a 9-year-old Cane Corso, arrived as a ticking time bomb of fear aggression, lashing out at any touch or unfamiliar presence. His world was shaped by internal medical issues that made every interaction feel like punishment, leaving him hyper-vigilant and defensive. For the first week, even the slightest approach triggered an explosive reaction, forcing me to earn his trust through patience and precision. Using pressure training and operant conditioning, we shifted his mindset—teaching him that he controlled his environment and that pressure wasn’t something to fear but a bridge to rewards. He learned to lean into discomfort, seeking the payoff rather than fighting against it. After six weeks, Brutus was unrecognizable—offering affection, mastering obedience, and embracing the world with newfound confidence. Today, he thrives among people and dogs alike, as playful as he was in his youth. His transformation proves that when pressure becomes an opportunity rather than a threat, a dog’s entire world can change.
