Found rottie mix, Hyattsville, MD--REUNITED WITH OWNER

Another found dog--this one in Hyattsville. Is anyone able/interested in holding on to this dog for a few days, to help keep him out of the shelter? Sweet guy, good with other dogs and people, wearing a collar, appears to be in good shape. If you know this dog, or are willing to keep him safe for a few days, please leave a comment!
