Shepherd Historic District Neighborhood Association

On Wednesday 2/10/2010, my sweet 4.5 year old dog, Cooper, went missing on Glen Canyon Drive in Garland, Texas.  She is a Black Shepherd Mix, with a creamy white chest and under coat.  She is incredibly well mannered, well trained on and off leash, and one of the most darling souls in the world.  She is 45-50 pounds, short-haired, deep chested, with long sprinter legs and a long "Pointer" type tail.  Please help me find my sweet Cooper.
