SPANAWAY, Pierce County — A Pierce County sheriff’s spokesman says deputies shot and killed two dogs after the animals attacked a woman in Spanaway and a man who tried to help her.

The News Tribune reports that the 65-year-old woman was taken to a hospital Wednesday for treatment of extensive arm injuries. The man also sought treatment.

Deputies say the woman was walking on a street when the dogs attacked without provocation. They were described as pit bulls. Deputies say the dogs turned on a 52-year-old man who went to the woman’s aid, biting his arm.

Sheriff’s spokesman Ed Troyer says a passer-by shot and wounded one dog, which ran off. Deputies found the second dog at the attack site and killed it. Troyer says the officers later tracked down and killed the wounded dog.

The case has been forwarded to prosecutors.
