Lost Dog 1-11-16: UPDATE

My dog has been missing since earlier today 1-10-2016. He went missing in the area of Riverside Drive Ext. near Old Mill Branch Rd and could now be in the areas of Walnut Tree Rd to Sharps Point Rd in the Fruitland MD area. He is a 2 year old Sharpee mix named Ripken. He has a blue Georgetown Hoyas collar. We can be reached at 443-235-5731 or warrenm0510@gmail.com. Anytime day or night if anyone thinks they may have seen him. He is friendly so hoping he found somewhere warm.
Please help us find him!
