Pit bulls live to be 10 to 16 years old, depending on the type. The American pit bull terrier typically lives to be 10 to 12 years old, while the American Staffordshire terrier and Staffordshire bull terrier live 12 to 16 years and 12 to 14 years respectively.
In general, pit bulls suffer from a variety of common hereditary health conditions that potentially affect their longevity. These conditions include congenital heart disease, cancer, parvo, cataracts, ligament rupture and hip dysplasia. As with any animal, pit bulls tend to live longer when they exercise regularly and consume a healthy, protein-rich diet.
