"My friend just rescued a dog on Wisc. Ave. - she was crossing from Q over Wisc. and saw the dog - a young Weimaraner named "Harp" (?) with tags with a phone number that rings to Southern Pines, NC. The dog also has a Petwatch number on his tag. Please call Rosie if you know whose dog this could be: 202 316 4102."
