PITTSBURGH - Authorities responding to a call about gunfire in Pennsylvania encountered a man walking out of a home where the door was kicked in and the porch was littered with shell casings, and they say he threatened to bite a police dog, barked at it and yelled "I'm gonna kill Fido."

Police say 39-year-old Shawn A. Seif of Homewood appeared to be staging a home invasion at about 1 a.m. Tuesday. Seif owns the home but didn't tell police that.

Seif is charged with tormenting a police animal, resisting arrest and marijuana possession. He is being held in Allegheny County Jail, unable to make bond. No attorney was listed on court papers.
