Last week, my neice was attacked by the neigbhbor's pitt bull. He allows his two pitts to run free (no fence, no leashed, no tie outs). My neice was walking thier Rottweiller in the cul de sac when the neighbor let his dog out to potty. The dog came after my neice, but their Rottie got between the her and the Pitt and kept the Pitt at bay until the neighbor could get control of him (about 3 minutes). My neice was bitten in the foot. The punctures went lean through her tennis shoe. But becuase of her Rottie, she wasn't hurt any worse. The neighbor called animal control himself to come and pick up the dog. It has been destroyed. In my opinion, Anthony, my sister's Rottie, is a real hero.
