3. Background

5. How the purpose of the dog changed how the dog was built in structure.

6. The Staffordshire bull terrier had its beginnings in England many centuries ago when the bulldog and Mastiff were used for the sports of bull-baiting and bear-baiting; in the Elizabethan era, breeders produced large dogs for these sports but later on the 100–120 pound animal gave way to a small, more agile breed of up to 90 pounds. The sport of dog fighting gained popularity in England in the early 19th century and a smaller, faster dog was developed. It was called by names such as "bulldog terrier" and "bull and terrier". The bulldog at that time was larger than the modern-day English bulldog we know today, weighing about 60 pounds. This dog was crossed with a small native terrier, related to the present-day Manchester terrier to produce the Staffordshire bull terrier weighing on average between 30 and 45 pounds.

7. Some of the Early Bloodlines Colby bloodline John P. Colby started the Colby bloodline in 1889 and they been going ever since. John P. Colby started with the best dogs that the immigrants had brought over Ireland and England. The Colby bloodline is known world wide and probably the oldest pitbull bloodline. Carver Bloodline Some of the most phenomenal performing dogs that we know of today comes from the Carver bloodline. Maurice Carver was born in 1916 and started working with dogs at a young age, possibly 10 or 11. Carver passed away in 1979, he had a lot of years of dog breeding. He was known for having a great instinct and an eye for what dogs to breed.

8. More of the Early Bloodlines Boudreaux Bloodline Gas house bloodline Since the 1930’s Boudreaux bloodline has stood the test of time and is the foundation of some of the best intelligent performance bloodlines. Boudreaux has produced some of the worlds most famous pitbulls. One of the most famous and widely quoted dogs as the foundation stock of PitBull Terriers in America was The Gas House Dog. The Gas House Dog, was a brindle dog with white blaze in face, white ring about neck, white breast and paws. He was the property of the late John McDonald, who at the time of ownership had charge of the gas-house stables in Boston .

13. The Myths and Facts Myth: "Pit Bulls have locking jaws." Fact: The jaws of the Pit Bull are functionally the same as the jaws of any other breed, and this has been proven via expert examination. Myth: “Pit Bulls have more bite pressure per square inch (PSI) than any other breed.” Fact: This is absolutely false. The highest pressure recorded from the Pit Bull was 235 lbs. PSI. The highest from the German Shepard was 238 lbs. PSI, and the highest from the Rottweiler was 328 lbs. PSI. The PSI tested in the Rottweiler is the highest on record for any domestic canine.

14. More Myths and Facts Myth: “The brains of Pit Bulls swell and cause them to go crazy”. Fact: Prior to the boom in Pit Bull popularity, the Doberman Pinscher was rumored to suffer from an affliction of the brain in which the skull became too small to accommodate a dog’s grey matter. This would, according to the rumor, cause the Doberman to go crazy, or “just snap” out of no where and attack their owner. This rumor could never be quantified, and indeed had no merit whatsoever. Now that the Doberman fad has run its course the Pit Bull has inherited the swelling brain myth. It is no truer now than it was during the Doberman’s fad days.

15. Temperament By nature, the APBT is an affectionate, anxious-to-please dog, but most people never hear that. Any publicity the breed gets is usually negative, including injuries to humans and other pets and proposed legislation banning “pitbulls.” Even if a confrontation is not the APBT’s fault, the fact that a “pitbull” is involved will surely headline the news item. Properly bred, socialized, and trained APBTs are among the least likely dogs to be human aggressive.

16. Strength The APBTs power and strength are the result of more than a century of survival under dreadful circumstances. Pound for pound, the APBT is an incredibly strong dog and a relatively small package. Constant control must be maintained at all times with even the friendliest APBT-perhaps because of his extreme friendliness. Unchecked exuberance could easily overpower an unsuspecting handler, even if the dog is exhibiting nonaggressive excitement.

17. Loyalty and Companionability The APBT makes a loving, trusting, an entertaining pet. He enjoys being with his humans and will devote his life to serving them. He is good-natured with children and very tolerant of their accidental roughness. He will play for hours with his human children, often sensing which ones are too young for extreme rough-and-tumble play. This makes the APBT a natural, competent guardian-a protector, not a perpetrator.
