"SPOKANE, Wash. (AP) - Spokane County sheriff's deputies used a stun gun on an attacking pit bull dog. It didn't stop, so they shot it with a .45-caliber handgun, and it still kept coming. They finally killed it with a blast from a 12-gauge shotgun.
The sheriff's office says the dog was killed early Wednesday as deputies responded to a domestic violence incident at a home.
Deputies arrested a 32-year-old man who had been drinking and threatened his family. Two daughters, ages 2 and 3, who were inside the house were unharmed and slept through the dog's shooting."
