Pit bulls are the most common dog breed seen in dog shelters around the country. In one shelter, more than 50% of dogs that came in that year were pit bulls. Most of the pit bulls brought in also showed signs of being subject to illegal dog fighting. For most of the 114 years that pit bull terriers has been recognized as a dog breed, pit bulls have been refereed to as the "nanny dog" because of their profound friendliness toward children and people. Since the 1980s the media has bombarded the public with propaganda against pit bulls due to the gangs immense interest in the dog breed used to protect, intimidate rival gangs, and fight the dogs for money. The gangs that use these dogs as a intimidating figure do not spay or neuter their dogs which result in an ongoing cycle. Eighty-six percent of all fatal attacks are by unneutered males. If a dog is raised to kill and has lived in very harsh conditions, you cannot expect the dog to be fully socialized and really friendly. The dog was raised to exhibit aggression. The pit bull was originally bred to be a cattle and wildlife dog, trained to track down hogs, to drive cattle and to be a family dog. A study found that 87.5% of the dogs identified by shelters wasn't the breed for which it was originally identified. Between 2002-2005, the shelter that took them in identified 11 dogs that were involved in fatality's as pit bulls, which was false because the dogs had absolutely no pit bull characteristics.
