That is not normal. As a matter of fact, I don't know since this condition I have never seen it. The best bet is to visit the veterinarian.
Firstly, there is no such thing as an ''English Staffordshire Terrier''. There is, however, Staffordshire Bull Terriers, English Bull Terriers, American Staffordshire Terriers and American Pit Bull Terriers - which all shed and are all individual breeds.
Since the 17th century where it emerged from a cross between Bull Terriers and other terriers of the time. At this time they were used for blood sports like bull baiting and bear baiting. These dogs provided the ancestral foundations for Staffordshire Bull Terriers, Bull Terriers, the American Pit Bull Terrier and the American Staffordshire Terrier. This common ancestor was known as the Bull and Terrier. After these bloodsports were eliminated in 1835 these dogs came to be used in dogfights.
Staffordshire bull terriers are up to 16 inches, American Pit Bull Terriers can grow to 18 inches, and American Staffordshire Terriers can grow to 20 inches tall.
Unfortunately, Staffordshire Bull Terriers were fought for human entertainment. People would often place bets on which Dog would win and the winning Dog would go on to fight again. Another 'blood sport' involving Bull Terriers was bull baiting, where a tethered Bull or Bear was killed by Dog's for human entertainment. The Staffordshire Bull Terrier and American Staffordshire Terrier (Pit Bull) were selected as the breeds used in these 'blood sports' because they are athletic, fast, agile and strong.
Pit Bull Terriers, or American Staffordshire Terriers, originated in the United States in the 1800's.
Any strong force can break the skull of a Staffordshire bull terrier.

The Staffordshire Bull Terrier was bred from muscular, but heavy dogs used for Bull-baiting and small, but fiesty local Terriers - combining the best parts of both types of Dog. The resulting Staffy-looking Dogs were fast, agile and strong; perfect for Bull-baiting. Staffordshire Bull Terriers were not bred from one or two particular breeds, just local Terriers and Dog's similar to Bulldogs.
This is a myth, Staffordshire Bull Terriers do not have ''lockjaw''. In fact, no breed does! Staffordshire Bull Terriers and American Staffordshire Terriers have exactly the same jaw formation as any other breed of dog. They do have incredibly strong muscles in their jaws but the condition ''lockjaw'' does not exist in any breed.

Expert scientific studies prove that the jaws of Staffordshire Bull Terriers are no different than any other breed of dog. There is no evidence that any kind of locking mechanism exists in the Staffordshire Bull Terrier or any other related dog breed.
Most Pit Bull Terriers, or American Staffordshire Terriers, are between 43-48cm (17-19in).
