Full face it should be oval in outline and be filled completely up giving the impression of fullness with a surface devoid of hollows or indentations, i.e., egg shaped. In profile it should curve gently downwards from the top of the skull to the tip of the nose. The forehead should be flat across from ear to ear. The distance from the tip of the nose to the eyes should be perceptibly greater than that from the eyes to the top of the skull. The underjaw should be deep and well defined.

Eyes

Should be well sunken and as dark as possible, with a piercing glint and they should be small, triangular and obliquely placed; set near together and high up on the dog's head. Blue eyes are a disqualification.

Neck

Should be very muscular, long, arched and clean, tapering from the shoulders to the head and it should be free from loose skin.

Body

Should be well rounded with marked spring of rib, the back should be short and strong. The back ribs deep. Slightly arched over the loin. The shoulders should be strong and muscular but without heaviness. The shoulder blades should be wide and flat and there should be a very pronounced backward slope from the bottom edge of the blade to the top edge. Behind the shoulders there should be no slackness or dip at the withers. The underline from the brisket to the belly should form a graceful upward curve.

Legs

Should be big boned but not to the point of coarseness; the forelegs should be of moderate length, perfectly straight, and the dog must stand firmly upon them. The elbows must turn neither in nor out, and the pasterns should be strong and upright. The hind legs should be parallel viewed from behind. The thighs very muscular with hocks well let down. Hind pasterns short and upright. The stifle joint should be well bent with a well-developed second thigh.

Color

Is white though markings on the head are permissible. Any markings elsewhere on the coat are to be severely faulted. Skin pigmentation is not to be penalized.

Movement

The dog shall move smoothly, covering the ground with free, easy strides, fore and hind legs should move parallel each to each when viewed from in front or behind. The forelegs reaching out well and the hind legs moving smoothly at the hip and flexing well at the stifle and hock. The dog should move compactly and in one piece but with a typical jaunty air that suggests agility and power.

Faults

Any departure from the foregoing points shall be considered a fault and the seriousness of the fault shall be in exact proportion to its degree, i.e. a very crooked front is a very bad fault; a rather crooked front is a rather bad fault; and a slightly crooked front is a slight fault.

Coat: The coat of the Bull Terrier should always be short, flat and
harsh, even being somewhat coarse to the touch. The hair should always be glossy
and should be close lying. This breed should have tight skin, never wrinkly or
saggy. Grooming this breed is fairly simple as the coat is very short. However,
the Bull Terrier should be protected from the cold.

Overview: The Bull Terrier is a cross between the Bulldog and the Old
English Terrier with a bit of Spanish Pointer in his bloodline. This breed
originated in 1830 to attack bull in this sport of combat. They were soon
replaced in 1850 with the White Cavalier and have since been used for many
different things. The Bull Terrier has been used as a guard dog, a ratter, a
herder, and a watchdog and does extremely well in all.

Character: The Bull Terrier is a lively breed but can also be lazy
and quiet at times. A very muscular and well-built breed, this dog has a very
sweet disposition and can be very affectionate. This dog requires an experienced
handler as they can become dominant without the right training and
socialization. The Bull Terrier is a very polite breed that is naturally
obedient, however does need extensive training and requires a great deal of
companionship.

Temperament: Fiery, energetic, and loving, this breed can also be
protective of his owner and his territory, giving off somewhat of a fearless
presence. This breed makes a good watch and/or guard dog. The Bull Terrier is
very hardy and sturdy and can tolerate quite a bit of child's play, however
should always be supervised, as Bull Terriers can be snippy if they are overly
pestered. With proper socialization and training, this breed can do well with
other dogs.

Care: The Bull Terrier does not require much grooming, and an
occasional brushing with a rubber brush should be sufficient. Hand plucking may
be necessary for dead hairs, but is usually cared for with a brush or comb. This
breed is an average shedder, shedding only around twice a year. Removing loose
hair should be simple when using a special rubber glove designed for such a
task. Ear cleaning is necessary to prevent any difficulties in the future.

Training: Being somewhat willful and very independent, the Bull
Terrier can be difficult to train. Obedience training should be started at an
early age to avoid any issues in the future. Being that this breed is prone to
dominance issues, firm and dominant handling is a must to prevent escalation
into aggression. Bull Terriers are very eager to please although they can be
very stubborn and difficult to train in any aspect.

Activity: The Bull Terrier is a very lively breed. A ball of fire,
this dog requires quite a bit of exercise to stay healthy and active. At least a
medium sized yard would work best as this breed has almost infinite energy. This
breed requires long daily walks, twice a day is best, as they can become
destructive if not given the proper stimulation and exercise requirements.
