Both Staffordshire Bull Terriers and Pit Bulls are strong, muscular dogs that have a reputation for being—and that's not always a good dog. They have similar looks and both possess a lot of energy, so it's easy to confuse the two. However, when it comes to Staffordshire Terriers and Bulldogs, there are some key differences that make them easier to tell apart.

In this article, we discuss everything you need to know about the Staffordshire Terrier and Bulldog, including their size, appearance and temperament.

Comparing Pitbulls and Staffordshire Bull Terriers

Pitbulls differ from Staffordshire Bull Terriers in size, color and build.


Bulldogs are the descendants of terriers that were crossed with bulldogs to create an agile and strong dog for fighting. In fact, the term "pit bull" is used so broadly that it can describe several dogs used for dogfighting. These dogs include Staffordshire Terriers, Staffordshire Bull Terriers and American Bulldogs. Pitbulls have historically been used in dogfighting and bullfighting, and are still used in illegal dogfighting today. This has earned them a reputation as aggressive dogs and led to their outright ban in some countries.

The Staffordshire Bull Terrier (also known as Staffies) is a descendant of mastiffs and pit bulls and was originally used for dogfighting and bullfighting – a sport that requires large dogs of 100-120 lbs. Eventually, however, the terrier was added to the mix, resulting in the smaller dogs we know today as Staffordshire Bull Terriers. Although workers are often referred to as "pitbulls," there are some differences between them.

One of the most notable differences between Staffordshire terriers and pit bulls is their size.

The head of a Staffordshire Bull Terrier generally appears rounder than that of a Pit Bull Terrier. Their heads are also short but broad, which is especially noticeable in the width of the forehead. Their ears are not as high as pitbulls.

Pitbull appearance varies widely within breeds—a pitbull's coat can be any color or pattern. However, Staffordshire terriers are very different. Their fur is usually a solid color – such as black, white, fawn, red or brindle. However, whites with any of these colors can sometimes be seen as well.

Pitbulls are brave but stubborn, with little tolerance for other animals. This is because they are often used in dog fighting, so they are naturally more aggressive towards other animals and have a strong desire to prey. This means they often see cats, dogs and other small animals as prey and are more likely to become aggressive towards them.

Despite their appearance, the Staffordshire Terrier is actually more loving than you might think. They are energetic, boisterous and playful, yet eager to please. They tend to behave well with dogs and other animals they know, but can be wary of dogs they don't know. In these cases, if they feel threatened, they will attack.

FAQ (Frequently Asked Questions)

Do Pit Bulls and Staffordshire Bull Terriers have Lock Jaws?

No, the locked jaw is actually a myth. Despite their reputation for locking their jaws, there is absolutely no difference in the shape, structure or configuration of their jaws from those of any other canine. Therefore, they do not lock the jaw, nor the ability to lock it. However, both dogs have a strong bite and do have a tendency to be firm and thus hold on to things longer than other dogs, which is where the jaw locking theory comes in. Their strength and determination come from their historical use in dogfighting and bullfighting.

Are Pit Bulls Dangerous?

Despite all the bad press they get, pitbulls are not actually considered to be naturally aggressive towards people. In fact, they are often considered very affectionate and loyal dogs. However, pit bulls can become dangerous if they are not properly trained and socialized, or have owners who encourage aggression or use them for fighting.

Are Staffordshire Bull Terriers Dangerous?

Staffordshire Bull Terriers tend to get a bad rap because of the confusion between pit bull and staff and their association with pit bulls and fighting dogs. However, despite having a much higher bite force than a Pitbull (328 pounds vs. 235 pounds for a Pitbull), they are not considered inherently dangerous dogs. Studies have actually found that they are no more aggressive than any other breed of dog. Instead, what affects whether they are dangerous is how they were raised and what their owners did to them.
