About Our Aggression Board and Train

Our aggression rehab program lasts between four and six weeks. Our trainers will work with dogs that are aggressive toward people and or other animals. This training focuses on dog growling, snarling, baring teeth, lunging, nipping and biting or even attack.

Your dog will stay with us for the duration of training. During training, we will work on obedience and control as we also work on your dog’s aggression issues. Dealing with aggressive dogs is NOT a quick fix; that is why training is much longer. Also, not all dogs can be rehabilitated. We cannot change the genetic composition, but we will give you absolute control of your dog and teach you how to handle it.

We specialize in dog and owner training

We have seen awesome results with our dog, who is a little bit of a nervous dog and 3 years old. Since completing the program, he has more confidence and we have more tools with how to handle him in all situations.
