More than a million Pits and Pit mixes are destroyed each year from Over breeding. Further, estimates don't include the misery and death pitbulls as the #1 dog fighting breed. Fought dogs that didn't die in the ring often suffer excruciating abuse, neglect and eventually death even worse than humane euthanasia.
The pittie project offers free spay an neutering to all pit and pit mixes. Their goal is to control the population of pits and pit mixes in shelters.
