According to the American Temperament Test Society, Pit Bulls pass their temperment test—conducted by a trained handler—87% of the time. That ranks them as 4th best of 122 breeds tested, meaning they are one of the most affectionate and least aggressive dogs. The sad reality is Pit Bulls are the most euthanized breed in the United States. In fact it’s disheartening and something we hope to change by enlightening you about this popular type of dogs.
