Salem County Prosecutor John Lenahan told the Today's Sunbeam newspaper of Salem that the officer was grazed and the dog was hit in the chest by a bullet. The animal was taken to the University of Pennsylvania's veterinary hospital in Philadelphia.
The prosecutor said a man in a duplex in the city of Salem, about 25 miles south of Philadelphia, remained in a standoff with police after 5 p.m. Wednesday.
The incident started about two hours earlier when two police officers and a county detective went to the home on a domestic violence call.
Lenahan said it was believed that a woman and children were in the home with the suspect, whose name has not been released.
