オールド・イングリッシュ・ブルドッグ
Most terriers, of the past and present, carried or carry a quarter to an eighth Old English Bulldog ancestry, for their purported courage to bear the bites of badgers and other prey they are meant to corner, dig for, or attack. Terriers that were not developed from crosses between the Old English Bulldog and earth-working dogs were of inferior quality and were valued far less.
