Missing Dog 5-2-15

A friend of mine is house sitting for another friend of mine while they are away on a cruise. The dog she was watching ran off Wednesday night around midnight. He is a short haired brown Chihuahua wearing a black collar. He was last seen around 1pm on Lennox Dr in the Breckenridge community. The dog is very shy and skiddish. Thank you! 410-202-3572
