At approximately 5:45 this evening a small Shih Tzu had been picked up from the Petco store in Prince Frederick by the foster parents. The dog slipped out of his collar and ran away heading towards Route 4. As he crossed Route 4, he was clipped by a car tumbled and continued running. He was last seen running through Winegardner GMC's lot towards the woods. He is a rescue from a hoarder and is very shy around people. He is white and black and had just been sheared of most of his coat. Any one that sees him please contact the Calvert County Sheriff's Department they have the information to contact the foster parents.
