Breed History
The Ambullneo Mastiff breeding program was conceived and created by Mark D. Reasinger Ph.D. in early 1980's California, and originally envisioned to develop an updated and improved version of the Bullmastiff.
The program was comprised of breeding an English Mastiff male to a Neapolitan Mastiff female where two pups from this litter were then bred to a Game Bred Pitbull. These 50/50 crosses were bred to a Bullmastiff. The result was a 45% Bulldog, 55% Mastiff cross. An American Bulldog/Pitbull was bred to a Bullmastiff producing a 70% Bulldog, 30% Mastiff cross. This was bred to the 45% Bulldog, 55% Mastiff cross to produce a 57.5% Bulldog, 42.5% Mastiff.Once the desired mesomorphic form, high intelligence, and behavioral traits with battle-tested performance had been achieved, the breed standard was solidified and the Ambullneo Mastiff was finally born.
Additional Details
General
The Ambullneo Mastiff is a large, massive and muscular dog that is a relatively new addition in dog breeds. Its California origin in the early 1980's is credited to Mark D. Reasinger, Ph.D..This breed is very graceful and gives the impression of great strength, while also being structured for endurance, short bursts of speed, and cat-like agility.This dominating dog has a large head with a medium to long muzzle. It has a large nose with wide nostrils. The dog displays a deep chest and broad shoulders along with a thick neck. Its bones are dense and heavy. The dog can stand anywhere from 24 to 29 inches and weigh an average 115-155 pounds when fully matured. It possesses great night vision and a keen sense of hearing. The short and thick coat comes in different colors.This breed has an inherent instinct to be protective of its family. It can spring into action moving all its body weight with the knockdown power of a locomotive to overtake and apprehend its target.As a family pet, the dog is calm and gentle. It is very alert and attentive to its surroundings and will make a good watch/guard dog.The Ambullneo Mastiff has been featured on Entertainment Tonight, Calendar, Timeout, N.Y. & Parade Magazine, as well as on an episode of Dogumentary TV.
This breed is not currently recognized by the American Kennel Club (AKC), however, the National Kennel Club (NKC) does recognize the Ambullneo Mastiff.
[NOTE: The AKC leans more toward show dogs while the NKC leans more toward working dogs.]
Color
This breed comes in many different colors. It can be seen in colors ranging from rare fawn to shiny pure black. Brindles are common and so are white marks on the chest and feet.Coat
The coat is short, dense, slightly harsh and thick. It is a low maintenance coat since the breed is low shedding.Personality
The Ambullneo Mastiff was developed for the sole purpose of protecting person and property, and it has played its role to perfection. The dog's natural fearsome appearance and inherent protective nature—together with a vigilant attitude—makes it a perfect guardian for home and property and proves an excellent deterrent for intruders. It has an even temperament when it is with its family. This dog is very gentle and kind with family members including children. It gets along well with other dogs and pets in the family. The dog has a natural eagerness to please its master. Loyal, gentle and dedicated to its owners, the dog is wary of human strangers (especially strange males). Also, other animal trespassers may not be tolerated by the dog. Early age socialization with people and places is necessary for this dog. The dog is not a frequent or habitual barker; it will only bark to signal something unusual around its surroundings. So if it is barking, it may be a good idea to investigate the reason. This intelligent dog breed is sensitive to one's tone of voice and should be spoken to in an assertive but not harsh voice. It does need an owner who can establish himself as the dog's pack leader. The Ambullneo Mastiff dog is a great family pet as well as a very strong, robust and loyal protector and guardian dog.Care
The coat requires minimal grooming. Brushing the coat once a week should be enough. Bathing is required when necessary. The dog's nails should be regularly trimmed. The owner should check its feet as it carries heavy weight.Training
This highly intelligent dog is very trainable as it loves to please the owner. It should be trained in an assertive and not harsh manner (the dog is sensitive to voice tone). This dog is not at all difficult to train.Activity
This dog is not as energetic as some of the other dog breeds, but it does need regular exercise (such as daily walks) to release its physical and mental energy. The dog is ideally suited to homes with a reasonably sized yard as it enjoys playing and patrolling its property. This breed is not suitable for an apartment lifestyle.

A Message from the Creator of the Ambullneo Mastiff
I started this journey of creation many years ago in the late 1970's while training K-9 dogs for the Sheriff's department.Although I loved the hard mouth, short coat, and size of the Rottweiler, I valued the intelligence, versatility and loyalty of the German Shepherd imports from West Germany. I had long been a fancier of the bulldog breeds (American Bulldog and American Pitbull Terrier) for their tenacity and ability to work alone. The self confidence they exhibited was truly a testimony to the quality of the breeding program behind these wonderful working breeds. Another one of my favorite dog groups was the Mastiff for its level head and complete devotion to its family, along with its large, intimidating size.At some point I realized that if dog fanciers like S.E. Moseley (father of the Bullmastiff), George Washington (American Founding Father and father of the American Foxhound), and Karl Friedrich Louis Dobermann (father of the Doberman) could create dogs to serve a particular purpose, then so could I. After all, I had been infatuated with dogs since I was 4 years old and read everything I could get my hands on regarding the subject. I also worked with dogs in one capacity or another since I was a boy (kennelman, veterinary assistant, dog trainer, decoy and breeder).Still, I wanted to run my ideas by the older professionals whom I looked up to and learned from in my lengthy tutelage. I shared my thoughts regarding this idea of the perfect guardian companion and the traits I wanted the Ambullneo Mastiff to possess. Then I began to look for the ideal candidate to represent each of the dog breeds involved.In total, I decided on five breeds that—together—would hopefully make the perfect blend of bulldog and mastiff. Some asked me “why bulldog” and “why mastiff,” and my answer was I simply realized that when dogs are used in a line breeding program, your dogs will eventually get smaller in size. Besides the large size of the mastiffs, I liked the guarding qualities and defense drive the mastiffs brought to the program.At the time, the Neopolitan Mastiff was very rare in Southern California, but they were prevalent in Italy, so that's where I originally went for the very best females money could buy. Procuring an English Mastiff in the U.S. for my breeding program was next to impossible because most people had never heard of such a thing at the time.I was constantly hearing, “What kind of mongrel are you trying to create, just buy an AKC dog.” People involved in kennel clubs were frightened to get involved for fear of being thrown out and turned into a pariah. However, with the right contracts created, stating their names without dog names ever being mentioned, and twice the cost they normally charged for the stud fee, deals were struck and the breeding program went from my mind, to a hand written blueprint, and finally came to fruition. This was only the beginning, but we were off and running.Though it was becoming very expensive, I was finally getting the opportunity to produce and observe the mastiffs I would select for the foundation of my program. I followed a strict protocol conducive to the above mentioned criteria and with every candidate that made the cut, the dogs got closer to what I had imagined them to be.Once the foundation mastiffs had been produced, I was ready for the infusion of the bulldog. Only after many months of continuous testing and comparing one dog to another was I able to make the decision based on the stud dog's progeny and ability to throw his many attributes. Although this was only half of the breeding program, we were well on our way.Later on the American Bulldog and Bullmastiff were introduced to the breeding program creating a 57.5 mastiff-42.5 bulldog cross; the F1 breeding stock was procured. I repeated this same program three times with different specimens and began to weave the F2, F3, and so on, until we had the dogs of today. Not long after our F7 breedings hit the ground, we were accepted for registration by the National Kennel Club and are very happy to be one of the many fine breeds to represent this fine establishment with our Ambullneo Mastiffs for the past 20+ years. That was many years ago and though we've faced many challenges, the breeding program has only gotten better as time goes on.I have been the shepherd guiding and guarding the breed from any and all adversarial entities. As the cost of dog food, kennel help, veterinary bills, water, electricity begin to skyrocket, monetary adjustments must be made and have been made. My staff, myself, and the many people involved in the breeding program will continue to produce the highest quality Ambullneo Mastiff puppies and trained adults available anywhere in the world.In the past forty years I've met many people—some who understand the complexity and importance of the continued high standards of my breeding program, and some who don't. I would like to thank all the people who have helped contribute to the success and quality of the Ambullneo Mastiff. If you are fortunate enough to own an Ambullneo Mastiff, you (like your dog) are a rare breed. And being a rare breed, the breeding program continues to grow as we create even better quality, more highly intelligent dogs. I will need the continued help and support from those people helping and supporting this wonderful breeding program. And I thank you for that.God bless you all.~ Mark D. Reasinger, PhD.
