According to the ADBA, the American Pit Bull is described to be medium-sized and has a short coat and smooth well-defined muscle structure, and its eyes are to be round to almond-shaped, and its ears are to be small to medium in length, typically half prick or rose in carriage. The tail is prescribed to be slightly thick and tapering to a point. The coat is required by the ADBA to be glossy, smooth, short, and stiff to the touch. Many colors, color patterns, and combinations of colors are acceptable to the ADBA, except that both the ADBA and UKC do not recognize merle coloring.

Dog fighting was used as both a bloodsport (often involving gambling) and a way to continue to test the quality of their stock. For decades afterwards, dog fighting clandestinely took place in small areas of Britain. These dogs arrived in America around 1845 to 1860, where the dog fighting practice had continuity. On February 10, 1898, the breed was recognized by the

For some time in the early part of the 20th century the UKC began to register the breed name with the word "pit" in parentheses (American (Pit) Bull Terrier), to facilitate public acceptance as an American Bull Terrier.

Temperament

The UKC gives this description of the characteristic of the American Pit Bull dog: "The essential characteristics of the American Pit Bull Terrier are strength, confidence, and zest for life. This breed is eager to please and brimming over with enthusiasm. Because most APBTs exhibit some level of dog aggression and because of its powerful physique, the APBT requires an owner who will carefully socialize and obedience train the dog. The breed's natural agility makes it one of the most capable canine climbers so good fencing is a must for this breed. This breed does very well in performance events because of its high level of intelligence and its willingness to work." The standard imposed by the ADBA and Old Family Red Nose Registry (OFRNR) considers human aggression a disqualification factor. The American Preservation Dog Registry (APDR) standard points out that "the temperament ''must'' be totally reliable with people". In September 2000, the United States

Centers for Disease Control and Prevention The Centers for Disease Control and Prevention (CDC) is the national public health agency of the United States. It is a United States federal agency, under the Department of Health and Human Services, and is headquartered in Atlanta, Georgi ...

(CDC) published a study that examined dog-bite–related fatalities (human death caused by dog-bite injuries) to "summarize breeds of dogs involved in fatal human attacks during a 20-year period and to assess policy implications." The study examined 238 fatalities between 1979 and 1998 in which the breed of dog was known. It found that "the data indicates that Rottweilers and pit bull–type dogs accounted for 67% of human DBRF og bite-related fatalityin the United States between 1979 and 1998" and that it was "extremely unlikely that they accounted for anywhere near 60% of dogs in the United States during that same period and, thus, there appears to be a breed-specific problem with fatalities."

Health

Due to their athleticism and diverse breeding background, the breed tends to be hardy, with an average lifespan of 12 to 14 years, longer than many breeds of a similar size. There are some genetic conditions to be watchful for. The breed tends to have bone diseases such as hip dysplasia, degenerative myelopathy and kneecap dislocation. The breed can also have skin problems, such as mange and skin allergies, because of its short coat. Other health ailments seen in the breed include thyroid and congenital heart defects. The breed tends to have a higher than average incidence of

s. American Pit Bull Terriers with dilute coat colors have not had a higher occurrence of skin allergies as other breeds. As a breed they are more susceptible to parvovirus than others if not vaccinated, especially as puppies, so vaccination is imperative beginning at 39 days old and continuing every 2 weeks until 4 months old. Then again at 8 months. Once a year after that, as recommend for all breeds. They are prone to Demodex Mange due to culling for performance. There are two different types of Demodex Mange, namely Localized and Generalized Demodex. Although it is not contagious it is sometimes difficult to treat due to immunodeficiency in some puppies. The Localized symptoms are usually loss of hair in small patches on the head and feet of the puppies. This type will usually heal as the puppies grow and their immune systems grow stronger. The second type which is Generalized Demodex mange is a more severe form of the sickness. The symptoms are more severe and include loss of hair throughout the entire body and the skin may also be scabby and bloody. Generalized are usually hereditary due to immunodeficiency genes that are passed on from Sire and Dam to their puppies. A simple skin scraping test will allow the vet to diagnose demodex mange. The most widely used method to treat Demodex Mange is

Colby Pit bulls

The Colby dogs are an ancient black-nosed bloodline that served as one of the pillars of the APBT breed. Considered one of the most important and one of the most famous bloodlines the Colby dogs were started by John Pritchard Colby in 1889, who acquired the best fighting dogs (

s) imported from Ireland and England. One of the most famous dogs of his bloodline was ''Colby's Pincher''. Pincher was known as an invincible fighting dog and was widely used as a stud dog. For this reason Pincher is present in the pedigree of the vast majority of APBT specimens. Today, the Colby dogs bloodline remains preserved by the family of John P. Colby.

or a family of bloodlines originating in Ireland, and known for their specific and unique reddish coloration. Many dogs of the OFRN strain has a copper-red nose and coat, red lips, red toe nails, and red or amber eyes. But not every American Pit Bull Terrier with these characteristics is necessarily an OFRN, since for this the dog must have a high percentage of the recognized bloodlines of this family in its pedigree. Pit Bull Red Nose-Tyson

In the middle of the 19th century, there was a strain of pit dogs in Ireland that were known as "Old Family". At that time, all the bloodlines were closely inbred with each family clan. Since red is recessive to all colors but white, the strain was known as "Irish Old Family Reds". When the dogs began coming to America, they were already showing the red nose. The "Old Family Reds" dogs found their way to America in the 19th century mainly via Irish immigrants though many in the United States did import the breed. Many strains have been crossed with the Old Family Reds at some time in their existence. Consequently, nearly any strain will occasionally throw a red-nosed pup. This means that not every red-nose dog is a true OFRN. The Old Family Reds produced more than their share of good ones unlike other strains are known. Old Family Reds were sought after for their gameness. The original strain continues to be bred. It was once renowned for its

, but now it is bred to maintain its unique reddish color. Some of the most reputable breeders of the past, such as Lightner, McClintock, Hemphill, Williams, Menefee, Norrod and Wallace have contributed to the preservation and development of the strain. Finally, as McNolty said in his ''30-30 Journal'' (1967) "Regardless of one's historical perspective, these old amber-eyed, red-nosed, red-toe-nailed, red-coated dogs represent some of the most significant pit bull history and tradition that stands on four legs today."

American Bull Terrier without the "pit" (a word that referred to dogfighting arenas) was the first name considered by the AKC, but quickly dismissed due to protests by English Bull Terrier's breeders. Yankee Terrier was another option, also dismissed. The name "Staffordshire Terrier" was chosen with the claim that the breed originally came from

under the name Staffordshire Terrier. Wilfred Truman Brandon founded the AKC Staffordshire Terrier Club of America (STCA). The Colby dog named Colby's Primo was one of the first to be regarded as an ideal model of the breed standard in the AKC. The AKC stud book was opened a few more times until it was last closed around the 1970s. In 1972 the AKC changed the name of the breed to American Staffordshire Terrier as it already intended to recognize the British Staffordshire Bull Terrier as a separate breed in subsequent years. Today a discussion persists whether the American Pit Bull Terrier and the American Staffordshire Terrier are two separate breeds or still the same breed. The fact is that Pit Bull and AmStaff breeders have distanced themselves from each other by pursuing different goals over the last 30 years, producing dogs with physical and temperament differences. Since 2015, the American Dog Breeders Association (ADBA), which has registered the American Pit Bull Terrier since 1909, considers the American Staffordshire Terrier to be a different separated breed. The UKC is the only kennel club at the moment to accept to register American Staffordshire Terriers as American Pit Bull Terriers. The UKC conformation champions are very similar to those of the AKC, as both clubs share many judges. The AKC has not accepted to register American Pit Bull Terrier as American Staffordshire Terriers since the late 20th century. To this day there are dogs called dual registered, dogs registered at the same time as American Staffordshire Terrier in the AKC and American Pit Bull Terrier in the UKC, due to past breeders who decided to keep the two pedigree registers parallel. Since 2015 the ADBA classifies most (or all) of these dual registered (AKC-UKC) dogs as American Staffordshire Terriers. The ADBA conformation champion dogs differ greatly from UKC and AKC champion dogs. The AKC standard does not accept red nose dogs. The UKC dogs and the AmStaff are generally heavier and more robust and bulky than the ADBA American Pit Bull Terrier dogs.
