A Waldoboro man is facing animal cruelty charges after a veterinarian found a dog with as many as 100 BB pellets embedded in its skin. Aaron Armstrong was arrested Thursday on a charge of aggravated animal cruelty and held on $25,000 cash bail. The stray black Labrador was found two weeks ago behind a house in Waldoboro and taken to the Lincoln County Animal Shelter. Someone adopted the female dog and took it to be spayed; that was when a veterinarian noticed strange lumps on the skin. X-rays showed dozens of BBs under the dog’s face, back, and legs.
