PITTSBURGH (AP) -- Authorities in western Pennsylvania say a neighbor shot and killed a dog after the animal attacked a 7-year-old boy in a Pittsburgh home.

The Pittsburgh public safety department says officers were dispatched to a home in the Esplen neighborhood at about 11:15 p.m. Saturday and found the child with head injuries. He was taken to Children's Hospital of Pittsburgh where he was listed in stable condition Sunday.

Police said the victim's 14-year-old brother ran to a neighbor for help after the attack by the pit bull, which belonged to a friend of the mother of the children. Officials said the neighbor, who has a license to carry a firearm, shot and killed the animal.
