Tosa vs Bull Terrier Miniature - Breed Comparison

Known also as the Japanese Mastiff, the Tosa hails from Japan. In fact, these dogs come from the Tosa Province, so the dog was named after the region where they were bred.

It is why they are sometimes referred to as Japanese Mastiffs. The Tosa is a rare dog breed and unfortunately, the dog is still used in Japan for dogfighting.

Thought to be a dangerous dog breed, it is restricted in some countries.

The breed was developed in the 2nd half of the 19th century, with a number of dog breeds being involved to bring about a more powerful, braver dog.

Less well known than the Bull Terrier, the Miniature Bull Terrier which actually follows the same breed standard, has a height of 35cm. The Bull Terrier and Miniature are classified as the same breed. The weight of the smaller Miniature is only about 15kg.

It was in the early 1800s that the Miniature Bull Terrier was developed, descending from the English Bulldog as well as the White English Terrier which is now extinct. This blend produced the Bull and Terrier, which was later shortened to the Bull Terrier. They came in a number of colors such as pure white, white and tan as well as white-and-black-patched or tri-colored.

Breed fanciers wanted a compact dog which looked much the same as the larger Bull Terrier. It was in 1938 that Colonel Glyn founded the Miniature Bull Terrier Club in England and the Miniature Bull Terrier Club of America was formed in 1966.

The Tosa is a large dog, but their sizes vary, and in fact, because of their fighting, they are actually divided into light-, middleweight and heavyweight classes.

Tail Chasing:

Some Bull Terriers develop a compulsive neurologic disorder where the dog turns round and round chasing his tail. As soon as you see this, try and distract him with an exciting game, because allowed to develop, it’s a habit that can become difficult to control.

Dental Disease:
