Police say two armed masked men entered Andy's Liquor Store on south Virginia Avenue shortly after 10:30 p.m. last night.
The men announced a holdup and began cleaning out the cash drawer.
That's when Spurs came between the robbers and his owner.
The robbers fired a shot, striking Spurs in the shoulder, and then fired at the owner, but missed.
The men then fled the store with an undetermined amount of money.
Police responded and rushed Spurs to a nearby animal hospital.
Police say Spurs is expected to make a full recovery.
The men remain at large.
Anyone with information is asked to call the Penns Grove Police Department at (856) 299-0055 or (856) 299-0304.
