Chief Inspector Scott Small said an autopsy would be done to determine the cause of death, The Philadelphia Inquirer reported. He said the 50-year-old woman was evidently killed by "severe head and face injuries," but it was not immediately obvious whether they were caused by the dogs or a human agent.
The husband, who reported finding his wife's body on the living room floor when he returned home at about 6:30 p.m., was taken in for questioning.
Several neighbors said the dogs had a reputation for viciousness. Gus Castro, 25, who lives across the street, said he was bitten Friday when the five dogs got out.
The dogs have been removed from the house.
