What is a pitbull harness?

Dog Harnesses Store states that a pit bull harness is a dog harness designed for the stocky body-type of the American Pit Bull Terrier, the American Staffordshire Terrier or dogs of similar builds. Dog harnesses are often used in place of collars for walking or exercising dogs.

Although dog harnesses are usually generic and fit any type of dog, some online vendors sell harnesses specifically designed for the stocky musculature of pit bulls and similar breeds. Pit bulls are bred to be athletic and to have a large musculature, so harnesses specifically designed for pit bulls and related breeds have extra strength to counteract the dogs' power and energy.
