Dog breeding is the practice of mating selected dogs with the intent to maintain or produce specific qualities and characteristics. When dogs reproduce without such human intervention, their offsprings' characteristics are determined by natural selection, while "dog breeding" refers specifically to the artificial selection of dogs, in which dogs are intentionally bred by their owners. A person who intentionally mates dogs to produce puppies is referred to as a dog breeder. Breeding relies on the science of genetics, so the breeder with a knowledge of canine genetics, health, and the intended use for the dogs attempts to breed suitable dogs.
Humans have maintained populations of useful animals around their places of habitat since pre-historic times. They have intentionally fed dogs considered useful, while neglecting or killing others, thereby establishing a relationship between humans and certain types of dog over thousands of years. Over these millennia, domesticated dogs have developed into distinct types, or groups, such as livestock guardian dogs, hunting dogs, and sighthounds.
The American Pit Bull Terrier (APBT) is a medium-sized, solidly built, short haired dog whose early ancestors came from England and Ireland. It is a member of the molosser breed group. The American Staffordshire Terrier and The American Pit Bull Terrier (APBT) by breed are from the same lineage; Staffordshires was the name given by AKC, and American Pit Bull Terriers by UKC. The real difference between the two breeds is 6–8" in height and 25–35 lb in weight; the American Staffordshire being the larger of the two.
The Bull Terrier is a breed of dog in the terrier family. They have large, egg-shaped heads, and small triangular eyes. There is also a miniature version of this breed which is officially known as the Miniature Bull Terrier.
The Bull Terrier's most recognizable feature is its head]citation needed[, described as 'egg shaped' when viewed from the front, the top of the skull is almost flat from ear to ear. Profile curves gently downwards from top of skull to tip of nose which should be black and bent downwards at tip. Nostrils are well developed and under-jaw deep and strong snout. The unique triangle-shaped eyes are small, dark, and deep-set. The body is full and round, while the shoulders are robust and very muscular and the tail is carried horizontally. They are generally white in colour, walk with a jaunty gait, and are popularly known as the 'gladiator of the canine race'.
The term pit bull is a generic term used to describe dogs with similar physical characteristics. Usually a "pit bull" is considered one of several breeds including the American Pit Bull Terrier, the American Staffordshire Terrier, the Staffordshire Bull Terrier, Bull Terrier or any mix thereof. In some parts of the world, the American Bulldog and Dogo Argentino are also classified as a "Pit Bull-type" dog, despite major genetic differences. Any dog that is mixed with a "bully breed" may also be called a "pit bull" including those that are descended from the English Bulldog, French Bulldog, Boston Terrier and Cane Corso. The pitbull is not a distinct breed which may make it difficult for experts to identify, and while mixed breed dogs are often labelled a "pitbull" if they have certain physical characteristics such as a square shaped head or bulky body type, visual identification of mixed breed dogs is not recommended by the scholarly community.
Several jurisdictions have enacted breed-specific legislation against pitbulls, ranging from outright bans on the possession of pit bull-type dogs, to restrictions and conditions on pit bull ownership. Research indicates that breed specific legislation is ineffective because it is not the breed of dog that is dangerous; rather, it is unfavorable situations that create dangerous dogs.

The Boston Terrier is a breed of dog originating in the United States of America. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed. Color and markings are important when distinguishing this breed to the AKC standard. They should be either black, brindle or seal with white markings. Bostons are small and compact with a short tail and erect ears.The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at times. The average life span of a Boston is around 11 to 13 years, though some can live well into their teens.
The American Staffordshire terrier also known as Amstaff is a medium-sized, short-coated American dog breed. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club as the American Staffordshire Terrier in 1936. The name was changed to reflect difference from the Staffordshire Bull Terrier of England.
Dog breeds are groups of closely related and visibly similar domestic dogs, which are all of the subspecies Canis lupus familiaris, having characteristic traits that are selected and maintained by humans, bred from a known foundation stock. The term dog breed is also used to refer to natural breeds or landraces, which arose through time in response to a particular environment that included humans, with little or no selective breeding by humans. Such breeds are undocumented, and are identified by their appearance and often by a style of working. Ancient dog breeds are some of the modern (documented) descendants of such natural breeds.
