Police said the officer — a one-year veteran of the force who was not identified — was canvassing a neighborhood looking for witnesses around 4 p.m. Saturday. When the officer went to a home in 900 block of Lombardee Circle in Glen Burnie the dog — a male Chesapeake Bay Retriever named Vern — "confronted" the officer in the front yard, police said. The officer then fired his weapon twice, killing the dog, police said.
