Zynga used to have a Pit Bull weapon on the social networking game Mafia Wars. However the animal-as-a-weapon was removed due to a request by a letter from the People for the Ethical Treatment of Animals (PETA). PETA argued that using a domestic animal as an attack dog could lead to the abuse of real-life pit bulls.
Currently pit bulls are the most abused breed of dogs (example: Michael Vick case). PETA acknowledge that it is just a game, but felt that the depiction of animal abuse glorified cruelty of pit bulls. PETA said that they will be ?sending vegan chocolates to Zynga founder and CEO Mark Pincus to thank him for his compassionate decision.?
