Pitbull-Type Dogs Are 20% of Dogs in the U.S.
Pitbull-type dogs are by far the most popular "strong breed" dogs in the U.S. - more popular than German Shepherds, Boxers, Rottweilers, Doberman Pinschers, Great Danes, Huskies, Mastiffs, and many other strong breeds. While some claim that pitbull-type dogs only represent around 6% of dogs in the U.S., in reality pitbull-type dogs are the 3rd most popular dog type adopted from shelters and the 5th most popular dog type registered by veterinarians. In fact, we estimate that pitbull-type dogs (and their mixes) account for up to 20% of dogs in the U.S. not only because of their shelter and veterinary counts, but also because of the fact that since "pitbull" is not a breed, the broad "pitbull-type" population includes 4+ unique breeds (and their many mixes) plus many other breeds and mixes that can get labeled as "pitbull-type" dogs due to their appearance. Below, we summarize the shelter and registration data used for our pitbull-type population estimate.
