American Staffordshire Terrier

Last updated: Aug 31 2023

The American Staffordshire Terrier is a medium-large, muscular, strong, and athletic dog that descends from early Greek Mastiff-type dogs that were used for dogfighting, hunting, protection, etc. In the early 19th century, these dogs came to England and were known as Pit Bull Terriers.

In England, Pit Bull Terriers were used as fighting dogs against bulls and bears. In 1835 these “sports” were prohibited, so people just started to fight dogs against each other. This continued on the American ground also, where these dogs were brought by immigrants from England, Ireland, and Scotland.

In America, selective breeding increased the weight of these dogs and enlarged their jaws. Americans wanted a bigger, more powerful-looking dog.

In America, American Staffordshire Terriers dogs were mostly used as working, all-around farm dogs and companions, but their negative reputation for being fighting dogs followed them. This is why they are often included in Breed Specific Legislation (BSL) that bans them.

Countries that have restrictions on Amstaff ownership are France, Spain, Portugal, Germany, Switzerland, Romania, Ireland, Denmark, Norway, Russia, Israel, and Singapore.

General Health

Their head is broad and square-shaped, their jaws are strong, and their eyes are set wide apart. The ears may be cropped. The body of the American Staffordshire Terrier is very muscular and strong, so make sure to train your AmStaff properly. If not trained properly, this dog will pull on the leash, and your walks could be frustrating.

The American Staffordshire Terrier is mostly known as an excellent family companion that thrives on being around their family. Amstaffs are the happiest when they're involved in all family activities, no matter what that activity might be; an intense playing session, a long walk, or just lounging on the living room sofa.

These dogs have a nasty reputation for being aggressive guard dogs, but the truth is that they are more likely to greet strangers with lots of love and kisses and will probably expect a decent amount of belly scratches. It is mostly their strong physique and a nasty reputation as aggressive "Pit Bulls" that intimidate strangers and make sure that they don’t come too close.

Amstaff

With that in mind, a lot of Amstaff owners say that these dogs are excellent when it comes to judging people’s character and they can easily guess people's intentions and because of that, they can be great watchdogs.

American Staffordshire Terrier vs Pitbull

The general term “pit bull” was used to describe a lot of dog breeds that were used for illegal blood sports and Amstaff is sometimes mistakenly called the Pitbull terrier. They have a similar physique and is certainly understandable why an average citizen might get these two breeds confused.

Pit Bull Terriers are a dog breed that is not recognized on a definite basis by most of the major cynology associations. The breed enthusiasts are trying to get this breed registered on a definite basis but they are encountering a lot of problems.

That specific dog breed is restricted in many parts of the world and some countries, or rather parts of some countries, like New South Wales in Australia, have restrictions that have mandatory neutering of this dog breed so it is practically impossible to breed the Pit Bull breed.

Pit Bulls have a negative image problem as being aggressive towards other dogs and animals. Breeding clubs and Pit Bull dog owners describe them as being completely reliable with people and they consider aggressiveness towards people a disqualifying quality.

Amstaff

There is an American Temperament Test Society or ATTS that tests the temperament of dogs, as it is clearly stated in their name. They mention that Pit Bulls have an 87,4% pass rate, and one of the most popular American family dog breeds, the Golden Retriever has a pass rate of 85,6%. It clearly shows that these dogs are friendly and unlikely to be aggressive towards people. We are mostly afraid of them based on their reputation and physique.

FUN FACT: Although they are known as separate breeds for over 50 years, the American Pit Bull Terrier and the American Staffordshire Terrier have a lot in common. They share a similar personality and activity level.

Grooming

The coat of the American Staffordshire Terrier is short, smooth, and easy to maintain. Regular weekly brushing using a firm-bristled brush will be enough.

This regular brushing will help manage shedding and will keep the coat clean and healthy. These dogs shed at a low to moderate rate. The coat can come in almost any color (white, black, brindle, blue, fawn, liver, etc.) and pattern, except merle.

Coats with more than 80% white, black, and tan, or liver are not preferred. The rest of the care is basic – trim the dog’s nails regularly, brush his teeth (American Staffordshire Terriers are known to have bad breath), and clean his ears.

Amstaff

FUN FACT: American Staffordshire Terriers usually don’t like to have their paws touched, so start touching them on purpose from day one. This way they will get used to the touch, and it will be a lot easier to take care of the paws later.

Training

The American Staffordshire Terrier is a highly energetic dog that requires regular, vigorous exercise. They need both physical and mental challenges. Routine exercise is very important. If American Staffordshire Terrier becomes bored or doesn’t have a proper outlet for all his energy, he will become destructive, or hyperactive.

Remember that the American Staffordshire Terrier has a strong jaw that can destroy all of your furniture.

FUN FACT: Amstaff dogs love to dig, pull and chew.

The American Staffordshire Terrier is a loyal, tolerant, smart, and playful dog that loves to be around his human family members. These dogs are deeply affectionate, and they create strong bonds with their humans. As with any other breed, early socialization is a must.

Training is a necessity, considering this dog’s physical strength and exuberance. They need a confident, assertive trainer.

Amstaff

Socialization

American Staffordshire Terriers have a reputation among dog owners as being lovely family companion dogs and pets, and they get along well even with children. That being said, they fit best in homes with a little bit of older children - over the age of six.

This dog breed is very powerful, and when they get carried on, they can play a bit rougher, which might result in unwanted accidents and injuries. Younger children are likely to poke and pull the dog, so it is very important to teach your kids how to properly and safely treat and approach animals.

Even if your dog is properly trained and socialized, playing time with children of all ages should always be monitored, no matter the dog's breed.

Amstaff and other animals

When it comes to other animals, it is important to pay special attention. Amstaffs can be aggressive to other dogs, especially those of the same gender. This is why American Staffordshire Terriers should never be left alone with other dogs that they don’t know.

Today, American Staffordshire Terriers are used as police dogs, guard dogs, or simply pets. Although these dogs are generally very friendly towards humans, some people fear them because of their muscular bodies and reputation for being fierce.

Amstaff

Health issues

The Amstaff is generally a healthy breed, but, as most breeds are, this breed is also prone to certain health conditions that (future) owners should be on the lookout for.

These dogs are prone to

  • hip and elbow dysplasia,
  • luxating patella,
  • hypothyroidism (a condition in which the thyroid gland doesn't produce enough of certain crucial hormones which can cause the dog’s metabolism to slow down),
  • cerebellar ataxia (a neurologic disease),
  • allergies,
  • heart diseases.

A healthy American Staffordshire Terrier has a lifespan of 12-16 years.

Breed History

The origin of the American Staffordshire terrier can be tracked as early as 19th century England. Dog breeders of that time used original bulldogs and terriers and crossed them to create a new dog breed that inherited the most “desirable” characteristics of each of those breeds.

The result of that crossbreeding was a fast and energetic terrier-type dog breed with the stubbornness of an original English Bulldog that also inherited its confidence. This newly created dog breed was called the bull-and-terrier Dog or a Pit dog since that is the main reason these dogs were created.

Amstaff dogs

Eventually, this dog breed was named in England as the Staffordshire Bull Terrier. Sadly, these dogs were mostly used for blood sports such as dogfighting and bullbaiting. Even though dogfighting was declared illegal across Great Britain in 1835, it very much continued since it was extremely difficult to enforce and uphold the law.

The bull-and-terrier dogs migrated to the United States of America at the end of the 19th century where they were named pit bull terriers and then renamed as American bull terriers.

The exact purpose is still unclear and there are some disputes on this subject, it is widely considered that the early Amstaff dogs were not mostly used as fighting dogs unlike their direct ancestors, but were mostly used as general farm dogs, hunting dogs, and companion dogs.

Amstaff dogs

With time, this dog breed was selectively bred to achieve larger dogs with bulkier build than their English cousins. Originally, this dog breed was registered by the American Kennel Club in 1936 by the name of Staffordshire Terrier.

They were later officially renamed in 1972 to have a clear distinction between the smaller English Staffordshire (today's Staffordshire Bull Terrier). Today, these two are registered as totally separate dog breeds.
