Bull Mastiff Info



     The known history of the Bullmastiff begins about the year 1860 in England.  It is probable that the story of the breed is really centuries old.  The Bullmastiff was bred to aid gamekeepers in protecting the game on large English estates.  Poaching on the estates was an expensive problem for the landowners, and it was the gamekeeper's duty to catch the thieves.  Gamekeepers needed a dog that could track quietly, cover short distances quickly, and pin and hold poachers without mauling them.

     Gamekeepers experimented with several breeds, looking to the mastiff, who was too slow, and then the bulldog, who was at the time a more ferocious dog than he is today--to ferocious.  Out of these breeds, the bullmastiff was born.  He combined the best of both breeds for the job required of him.  He is now primarily a family companion with a calm, dependable disposition when properly trained and socialized.

                                                Breed Standard


                                                 General Appearance

That of a symmetrical animal, showing great strength, endurance, and alertness; powerfully built but active.  The foundation breeding was 60% Mastiff and 40% Bulldog.  The breed was developed in England by gamekeepers for protection against poachers.


                                 Size, Proportion, Substance

Size- Dogs, 25 to 27 inches at the withers, and 110 to 130 pounds weight.  Bitches 24 to 26 inches at the withers and 100 to 120 pounds weight.  Other things being equal, the more substantial dog within these limits is favored.

Proportion- The length from tip of breastbone to rear of thigh exceeds the height from withers to ground only slightly, resulting in a nearly square appearance.



Expression- Keen, alert, and intelligent.

Eyes- Dark and of medium size.

Ears- V shaped and carried close to the cheeks, set on wide and high, level with occiput and cheeks, giving a square appearance to the skull; darker in color than the body and medium in size.

Skull- Large, with a fair amount of wrinkle when alert; broad, with cheeks well developed.  Forehead flat.  Stop is moderate.

Muzzle- Broad and deep; its length, in comparison with that of the entire head, approximately as 1 is to 3.  Lack of foreface with nostrils set on top of muzzle is a reversion to the Bulldog and is very undesirable.  A dark muzzle is preferable.

Nose- Black, with nostrils large and broad.

Flews- Not too pendulous.

Bite- Preferably level or slightly undershot.  Canine teeth large and set wide apart.


                                              Neck, Topline, Body

Neck- Slightly arched, of moderate length, very muscular, and almost equal in circumference to the skull.

Topline- Straight and level between withers and loin.

Body- Compact.  Chest wide and deep, with ribs well sprung and well set down between the forelegs.

Back- Short, giving the impression of a well balanced dog.

Loin- Wide, muscular, and slightly arched, with fair depth of flank.

Tail- Set on high, strong at the root, and tapering to the hocks.  It may be straight or curved, but never carried hound fashion.

Shoulders- Muscular but not loaded, and slightly sloping.

Forelegs- Straight, well boned, and set well apart; elbows turned neither in nor out.

Pasterns- Straight, feet of medium size, with round toes well arched.  Pads thick and tough, nails black.

Hindquarters- Broad and muscular, with well developed second thigh denoting power, but not cumbersome.  Moderate angulation at hocks.  Cowhocks and splay feet are serious faults.


                                                     Coat and Color

Coat- Short and dense, giving good weather protection.

Color- Red, fawn, or brindle.  Except for a very small white spot on the chest, white marking is considered a fault.



Free, smooth, and powerful.  When viewed from the side, reach and drive indicate maximum use of the dog's moderate angulation.  Back remains level and firm.  Coming and going, the dog moves in a straight line.  Feet tend to converge under the body, without crossing over, as speed increases.  There is no twisting in or out at the joints.



Fearless and confident yet docile.  The dog combines the reliability, intelligence, and willingness to please required in a dependable family companion and protector.
