Bull Terrier

Appearance
The Bull Terrier's most recognizable feature is its head, described as 'egg shaped' when viewed from the front, almost flat at the top, with a Roman muzzle sloping evenly down to the end of the nose with no stop. The unique triangle-shaped eyes are small, dark, and closely set. The body is full and round, while the shoulders are robust and muscular and the tail is carried horizontally. It walks with a jaunty gait, and is popularly known as the 'gladiator of the canine race'.
There is no designated height or weight for the breed but the average is, Height: 51-61 cm (20-24 inches), Weight: 20-38 kg (44-85 pounds) The Bull Terrier and the Miniature Bull Terrier are the only recognized breeds that have triangle-shaped eyes.
Temperament
Because of their power and difficulty to train ,"bullies" are not ideal for a first-time dog owner. However, their physical strength is matched by their intelligence, which makes them thoroughly reliable pets. Both body and mind need to be kept active and they can be fun and playful. The Bull Terrier is known to show aggressiveness towards other dogs, usually that of the same sex.
Pure Bred Bull Terriers can be extremely strong willed and dominant, especially males. In some cases professional level leadership and training is a necessity on a daily basis to prevent your dog from becoming an aggressive dog towards both humans and dogs. A Bull Terrier is not your average dog, this is a mentally and physically strong breed. Strict leadership and discipline regiment should be engaged from day one of ownership. Your Bull Terrier may seem like playful and mischievous puppy at first, but owners should be very aware to look and recognize aggressive and dominant behavior even in the first 6 months.
They are typically very affectionate dogs that love human company. Older (mature) Bull Terriers are particularly good with children, and usually have a high pain threshold, which reduces the risk of injury to children from a defensive bite. Younger dogs, however, may regard children as playmates and because of their strength could cause inadvertent injury. They are protective of children in their charge, and the females are especially noted for this. Bull Terriers can make formidable guard dogs while their owners are away.
Health
All puppies should be checked for deafness, as this sometimes occurs (most commonly in pure white dogs) and is difficult to notice, especially in a relatively young puppy. Many Bull Terriers have a tendency to develop skin allergies. Insect bites, such as those from fleas, and sometimes mosquitoes and mites, can produce a generalized allergic response of hives, rash, and itching. This condition can be stopped by keeping the dog free of contact from these insects, but this is definitely a consideration in climates or circumstances where exposure to these insects is inevitable. Their lifespan is somewhere between 10 and 14 years, although they can live longer - a male bull terrier house pet in South Wales, UK by the name of "Buller" lived to the age of 18 years. The oldest female Bull Terrier on record is an Australian house pet dubbed "Puppa Trout" who remained sprightly into her 17th year. The second oldest female Bull Terrier on record is "Boots Moon Stomp Stout (Crain)" of Denver, Colorado USA. Boots lived to be 16 years of age.
The Bull Terrier's coat is easy to maintain, but grooming can keep it in near-perfect condition. Adding oils to their meals can also vastly improve the quality of their coat. The Bull Terrier requires a fair amount of exercise, but overworking the dog at a young age will cause strained muscles. Older dogs do require exercise, but in small doses, whereas younger ones will be happy to play for hours on end. The breed is renowned for being extremely greedy; be sure to maintain a good balance of exercise and food, or the dog can become overweight. Also, be sure to check ears, eyes, nose and mouth every day for signs of infection, they can also suffer from a bad heart.
Common Ailments: Deafness, Umbilical Hernia and Acne. Bull Terriers can also suffer from obsessive compulsive disorder, such as tail chasing, self mutilation, and obsessive licking.
History
About 1850, James Hinks started breeding "Bull and Terriers" with "English White Terriers" (now extinct), looking for a cleaner appearance with better legs and nicer head. In 1862, Hinks entered a bitch called "Puss" sired by his white Bulldog called "Madman" into the Bull Terrier Class at the dog show held at the Cremorne Gardens in Chelsea. Originally known as the "Hinks Breed" and "The White Cavalier", these dogs did not yet have the now-familiar "egg face", but kept the stop in the skull profile.

Due to medical problems associated with all-white breeding, Ted Lyon among others began introducing colour, using Staffordshire Bull Terriers in the early 20th century. Coloured Bull Terriers were recognised as a separate variety (at least by the AKC) in 1936. Brindle is the preferred colour, but other colours are welcome.
Along with conformation, specific behaviour traits were sought. The epithet "White Cavalier", harking back to an age of chivalry, was bestowed on a breed which while never seeking to start a fight was well able to finish one, while socialising well with its "pack", including children and pups. Hinks himself had always aimed at a "gentleman's companion" dog rather than a pit-fighter -- though Bullies were often entered in the pits, with some success. Today the Bullie is valued as a comical, mischievous, imaginative and intelligent (problem-solving) but stubborn house pet suitable for experienced owners.
