Mammut Bulldog Breed Standard


The bulldog’s were created for the sport of bull baiting in the 1800’s and since the out law of the sport the bulldog has become more and more extreme due to breeders focusing on the overall appearance and public appeal of the bulldog as opposed to the strong working quality they once had.

The Mammut Bull is a recreation of the longer haired old style working bulldog. It is known that in certain regions of the country there were long haired bulldogs observed (for climate purposes) the longer hair served a working purpose to protect the dogs from harsh climates, cold and hot and also from attacks from animals.

The modern day Mammut Bull is originally a German bloodline comprised of 100% bulldog (American Bulldog, Bandogge, English Bulldog, Olde English Bulldogge and Bullmastif)

The Mammut Bull is strong, courageous with a stronger athletic look. The dogs are still very bulldog in appearance but are leaner, free breathing and of course with a longer coat that often appears as feathering around the ears, back of the legs and tail. Straight tail is preferred and left intact, kinked or deformed tails are docked, but the breed is not to be altered in any other way (no ear cropping or dewclaw removal). Muzzle is longer than the English Bulldog but is not to exceed the length of the skull. The dogs have a defined stop and a squared appearance with the skull and muzzle. Ideal bite is under 1/4 inch undershot with all teeth present (broken teeth are not faulted). Paws are large and compact, hips are equal to shoulders in width. Legs are strong, and well defined. The dogs are overall muscular and build for strength and agility.
