History

american staffordshire terrier - historyThe American Staffordshire Terrier is a part of all the confusion surrounding the group of “pit bulls”. The American Staffordshire Terrier is directly related to the English Bull Terrier and English Terrier. The breed of the English Staffordshire Terrier was bred in the early 19th century in the West Midlands. It was not until later that the breed came from Staffordshire. These English Staffordshire Terriers are also the source of contention by breeders who insist it was the Fox Terrier, White English Terrier, Tan and Black Terrier that are the ancestors of the English Staffordshire Terrier.

These terriers (AKA pit bull terrier) came to the United States in the mid 1800’s. By the late 1890’s they were accepted by the United Kennel Club (UKC)as the American Pit Bull Terrier – a new and distinct breed. There were also some that were accepted into the AKC as the Staffordshire Terrier. In England they were still known as the American Staffordshire Terrier. When the AKC accepted the breed in 1936 they were given a new standard, new purpose and new group – the terrier. In 1969 the American Kennel Club recognized these dogs as American Staffordshire Terriers and refused to recognize the American Pit Bull Terrier. The name was changed to move the breed away from its characterization as a bull fighter and to distinguish it from the smaller English Staffordshire Terrier. All American Staffordshire Terriers are directly related to the American Pit Bull Terriers.

american mastiff - historyThe history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

Description

american staffordshire terrier puppy - descriptionThe American Staffordshire Terrier is a strong, powerful dog – stocky, muscular and graceful. At one point in time the American Staffordshire Terrier and the American Pit Bull Terrier were considered to be the same breed. Even today there are those that make that argument, but they have been recognized outside the AKC as separate breeds. The AKC only recognizes the American Staffordshire Terrier and not the APBT. However – even though there have been decades of separation in breeding the American Staffordshire Terrier and the American Pit Bull Terrier are the very same dogs genetically.

The American Staffordshire Terrier has a broad skull, high set ears and pronounced cheek bones. Their ears should not be cropped by AKC standards and their eyes are far apart, round and dark. With a medium sized muzzle and a heavy muscular back, they are as powerful as they look, if not more so. Most have black noses. The AmStaff has a broad, deep chest with wide set forelegs and compact feet. The tail is short and tapered and it should not be docked.

With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Characteristics

american staffordshire terrier dog - characteristicsThe American Staffordshire Terrier is a loving, gentle dog that wants nothing more than to be with and please his people. Contrary to his reputation as a “killer”, this dog is actually a lover. They are great with children and want to be a part of the family. They even think they are lap dogs, regardless of their size. They are never going to be aggressive toward people and even though they are not one-person dogs, they are loyal, and they are devoted to the family and the “leader of the pack”.

This breed can tell who is their friend and who is not. They are not aggressive, but they will protect their own. They are courageous, confident, attentive, bold and strong-willed. The AmStaff gets along with other dogs most of the time, but they will never back down from a challenge and should never be left unsupervised with another dog. They should not be loose in a neighborhood or at a dog park. No matter how much you trust your American Staffordshire Terrier they can be killers in any fight with another dog.

In addition to this you must socialize and train your AmStaff. You need to be the pack leader and be in control. The AmStaff wants to please you so for a strong leader they will respond positively to positive training. They are intelligent and pick up quickly on what you want them to do. However, they are incredibly strong physically so training them to heel and walk with you obediently is a must. A well trained and exercised American Staffordshire Terrier is a happy dog and a loyal family dog.
