Bullmastiff Breed Standard
Working Group

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.

Head

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--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.

Forequarters
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
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.

Gait
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.

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

Bullmastiff(斗牛马士提夫犬) [简介] 这是一种匀称的动物，显示出极大的力量、耐性和机敏。非常强大而且活跃。他是具有60%马士提夫犬血统和40%英国斗牛犬血统。这个品种是在英格兰培养出来的，是猎场看护人培养了对付偷猎者的。

[体型] 大小：雄性肩高约25~27英寸，体重在110~130磅；雌性肩高约24~26英寸，体重在100~120磅。如果其他部分都一样，在上述范围内，身体越坚实越好。比例：体长稍微超过身高一点点，所以身躯比例接近正方形比例。

[头部] 表情：热烈、机警且聪明。眼睛：颜色深、中等大小。耳朵：V字形，折向面颊，位置高而宽，与头顶及面颊齐平，使脑袋看起来呈正方形；颜色比身躯的颜色深、中等大小。脑袋：巨大、警觉时有清晰的皱纹；宽且面颊丰满。前额平坦。止部：适中。口吻：宽而深；其长度，与整个头部相比，大约是1比3。缺乏前脸、鼻孔位置高（返祖现象，近似英国斗牛犬），属于严重缺陷。深色的口吻比较理想。鼻镜：黑色，鼻孔大而宽。上唇：不过分下垂。咬和：钳状咬和或下颚突出式咬和。犬齿巨大、距离较宽。

[颈部、背线、身躯] 颈部：略拱、中等长度、肌肉非常发达，直径几乎与脑袋相等。背线：马肩隆到腰部之间，直而平。身躯：紧凑。胸宽而深，肋骨扩张良好。背：短，给人的印象是非常稳定和谐。腰：宽、肌肉发达、略拱，腰窝深度清晰。尾巴：尾根位置高，根部粗壮、末端靠近飞节。可以是直的或卷曲的，但不能象猎犬的样子。

[前躯] 肩部：肌肉发达但不臃肿，适度倾斜。前肢：直、骨量充足、位置适当分开；肘部既不向内弯、也不向外翻。脚腕：直。足爪：中等大小，圆；脚趾圆拱；脚垫厚实坚硬；趾甲为黑色。

[后躯] 宽而肌肉发达，第二节大腿发达，显得有力，但不笨重。飞节角度适中。牛肢和兔形足都属于严重缺陷。

[被毛] 短而浓密，能适应各种气候。

[颜色] 红驼色、或许有斑纹。除了在胸部有非常小的白色污迹外，白色斑纹属于严重缺陷。

[步态] 舒展、平滑、有力。在侧面观察，后躯和驱动力来自正确的后肢角度。背线保持水平和坚实。无论来还是去，都保持直线运动。足爪趋向身体下方，但不交叉。速度增加时，飞节既不向内弯，也不向外翻。

[气质] 勇敢、自信且顺从，这种狗结合了可靠性、聪明和积极。作为可靠的家庭伴侣和护卫是再好也没有了。
