About Us


Welcome to Dark Dynasty K9s Home of The General and World Famous Hulk

DDK9’s was founded by Marlon Grennan in 2004 and is family own and run by Marlon and his wife Lisa Grennan located on a breath taking 150 acres in the beautiful White Mountains of New Hampshire. The DDKLine family continues to grow as more incredible people are brought onto the team – Derick, AP, Branden, Lenny, Kasey and more part time employees help with the daily operation of the business.
We are known for breeding and training the finest XL American Pitbull Terriers and proudly promote the well-being and reputation of this working breed with each carefully raised puppy and well trained dog in our growing family.

We know the relationship a person chooses to have with his dog determines the dog’s behavior. Marlon learned this first hand when he adopted an abused rescue dog, Damon, and time and time again Damon proved what every dog needs and wants is a firm consistent leader….the leader of the pack. Marlon and DDK9’s exemplify this role.

Learning to be the leader of the pack, you will not only bring out the best in your dog, you will bring out the best in yourself. As you master this way of life, you will restore dignity and responsibility to the special relationship between dog and man.
“If we can change one mind a day, we have succeeded.” -DDK9’s
The fact that Marlon is the son of world famous Reggae innovator Winston Grennan lends some insight into where Marlon’s strong leadership qualities and pursuit of excellence come from. Just as Marlon seeks to create the best quality in his breeding and training techniques, his father also sought beyond the pre-existing norm. Winston did not just play Reggae. He is credited with creating the “One-Drop” beat which quickly propelled the little known music into the international mainstream.

Just like Winston, Marlon has a clear vision for what is yet to be accomplished in the world of breeding and training. Like his father he is driven by a love of what he does and a pursuit of excellence. He is proud to say not a day goes by that his dogs are not admired for the exceptional qualities they exhibit in everyday life.

We used the best of all the finest bloodlines to create the world famous DDKLine. The result is a well-balanced calm family dog also capable of becoming a top of the line working dog. DDK9’s dogs can be trained for any level of protection including for high level security or family and personal protection.

“Just as my father created his own style of music I intend to create a new direction with my dogs”

“The difference between DDK9’s and other kennels is that here, there really are no kennels. We take daily pack walks of 15+ dogs, males and females, all intact. All of our dogs live together without fences, barriers or physical restrictions. Only in 2014 did we construct a kennel for clients dogs in training, our own personal dogs all live indoors with us as a part of our family. It is the daily and lived structure of consistent and proper leadership that gives them the security and direction they need. This, coupled with my experienced understanding of dog psychology and confident leadership (understanding of myself) creates a healthy balance among the dogs. In a well-balanced family or pack, the best qualities in each are nurtured and every member can become their best. Much like people, when this “character” is nurtured and cultivated in a dog, he will carry it with him in every situation and for life.

No dogs bred or sold for illegal purposes!!! Must be 21+ to purchase a puppy or protection levels of training. contact us!
