Two children bit in family dog attack

"My son and his daughter and I were walking their dog, and the dog literally came out of the house and attacked the dog and my son. And after that we're kind of leery about the dog because he's so out of control, you don't know what he is going to do," said a neighbor.

They now call Xavier a hero for calling 911.

"I told them something is going on at this house, and because everybody is yelling animal and somebody is hurt, and I want police and at least animal control here," he said.

Maricopa County Rabies and Animal Control are responding to the scene and plan to euthanize the pit bull immediately at the request of the family.
