Why train your reactive or aggressive dog with play?

Training through play isn’t a marketing gimmick — it’s the superior option.

The power of play cannot be understated in regards to behavior modification. I can talk about the benefits of play regarding aggression or reactivity for hours and still have more to say. The first thing of notice is that play isn’t just an activity where you throw a ball for a behavior, its a fundamental drive that is just as crucial as eating or sleeping and an emotional state (reference). When training an aggressive dog with food, many times you will see the dog take the food followed by them immediately reverting back to being aggressive, that is because they didn’t actually perceive the food as reinforcing in that moment and therefore no learning occurred. With play, a dog cannot play and be aggressive at the same time, nor can a dog be fearful. This allows us to peak directly into knowing what the emotional state of the dog is without thinking “he can snap”. Bringing what the dog is fearful/aggressive of into the context of play changes how the dog see’s things emotionally instead of focusing on behaviors.


  • Play is not as simple as just throwing the ball or tugging. I am talking about creating a game with rules, penalties for not following the rules, cooperation and competition. The only way to accomplish this is to create a game around your individual dog’s genetics and create something more motivating than anything in the world. For example, a dog with a high prey drive, what king of prey drive? Chasing, stalking, fighting etc… We will identify exactly what your dog loves and build the motivation as high as we possibly can, then control it.

  • After building the right motivation through play, we shift our focus to obedience. While most trainers start with commands like “sit,” we begin with impulse control, followed by the “drop it” command — where the dog must release whatever is in their mouth.

    “Drop it” becomes our window into teaching any command you personally want. The only mandatory commands in our program are:

    • Recall

    • Leave it

    • Drop it

    Everything else — like a “heel” command — is optional and tailored to your goals.

    • Deeper understanding of learning theory; operant and classical conditioning, motivation, how prediction works etc.

    • Deep understanding of dog’s emotions, how they work and how to change how they perceive what they’re aggressive/fearful towards

    • genetics vs learned behaviors, we must identify if its genetic or learned. If its learned we can change entirely how they perceive what they’re aggressive/reactive towards. if its genetic, we can control and manage the dog using obedience.
