A big part of eradicating your dog’s behavior is teaching you how to connect with your dog on the animal level instead of the human level. The relationship needs to be one of balance, trust, respect, structure, and leadership. In 1980 Leonard met Cesar Milan who was just beginning his journey as The Dog Whisperer. Cesar helped Leonard understand the pack mentality and how to work with dogs that are aggressive. Cesar gave Leonard a strong foundation. Leonard will always be grateful for the amount of time Cesar spent with him and the dog’s in Leonard’s pack. Leonard still use Cesar’s way for training aggressive dogs and dogs that need good manners.


While your dog is here, he is training with Leonard all day long. Not stuck in a cage all day. Your dog will learn, run and play with his pack of dogs at the beach.

What clients have to say

 Dominant Dogs Helped My Dog and Me When Other Trainers Said The Only Answer Was To Put Him Down.


Diane's Pit Bull had aggression issues and problems with attacking humans and dogs.

 We were losing hope on finding a dog trainer to help us with my Service Dog “Bub”. I contacted over 5 different dog trainers to help me with my problem of Bub’s aggression issues but not one wanted to meet or help me. They all said they did not have the knowledge or expertise to help me with a service dog and aggression issues.


Nancy's service dog, Bub was dealing with aggression issues.

 I was not able to take Princess to the park, go for a walk, or have anyone in our house without putting her away. We now go to the park almost everyday and throw the ball for her. She is completely focused on what we ask her and so well mannered. She doesn’t even glance at other dogs or people passing by.


Jenny's German Shepherd was aggressive and fearful. They were looking to find a new home for her before Doggie Boot Camp.

 Dixon was uncontrollable – he went ballistic over [everything]. Our vet wouldn’t see him unless he was sedated, and we had issues every time someone came to the house (whether he had met them or not). Within about 5 minutes, Leonard had him quieted down and relatively calm. Within 20 minutes, Dixon was behaving off leash (which we NEVER thought he would be able to be).

Stacia and Larry

Larry had to walk Dixon at 4am as to not expose him to so many outside triggers and set the dog off.
