They have a reputation for pugnaciousness, and when challenged by another dog it is characteristic of them to not back away. It is recommended that puppies receive early socialisation; certainly before 18 months. Staffords are healthy and robust dogs with a life expectancy of 12–14 years. Hereditary eye conditions, including L-2 Hydroxy Glutaric Aciduria (L-2HGA) and Hereditary Cataract (HC-HSF4Hereditary, are known to occur in the breed. In an effort to produce a lighter, faster, more agile dog with the courage and tenacity of the Bulldog, breeders outcrossed with local terriers and ultimately achieved success.The second less widely held theory is that the Old English Bulldog was not crossed with terriers; rather, the Stafford as a breed began with direct descendants derived from generations of selective breeding of early Bulldogs which produced a smaller dog with a more athletic build.
