DUQUESNE, Pa. - Authorities say they have removed 30 pit bulls and the remains of a badly mauled puppy from a western Pennsylvania home, and they are investigating whether dogfighting was going on.

Many of the dogs in the Duquesne home had severe injuries, said Katie Waters, an investigator for Animal Friends of Ohio Township. The injuries appeared to have been inflicted by other dogs, she said.

Paul McIntyre, chief of Triangle Pet Control Service Co. of McKees Rocks, described the puppy as "chewed up." He and Assistant Police Chief Scott Adams said they were investigating whether there had been dogfighting at the home.
