The popular Facebook game, Mafia Wars, recently announced that animals were going to be a new "fully-fledged combat item class." The new animal weapons include lions, tigers, and pit bulls.

Reinforcing stereotypes of pit bulls as dangerous animals only fuels breed specific legislation and the mystique of dog fighting, costing innocent dogs their lives.

Mark Pincus, CEO of Zynga, the company that created Mafia Wars named the company after his own American bulldog, a breed that is often maligned alongside "pit bull" type dogs.

Ask Mr. Pincus to protect bully breeds by not promoting negative stereotypes in his games.
