ブルテリア
The Bull and terrier is an extinct type of dog. It was a crossbreed that was the progenitor of several modern standardised breeds (Bull-type terriers), including the Bull Terrier, Miniature Bull Terrier, Dogo Argentino, Staffordshire Bull Terrier, American Pit Bull Terrier and American Staffordshire Terrier. Bull and terriers were crossbred primarily from the Old English Bulldog and one or more varieties of Old English Terriers.
