Found Puppy

Last week we were coming home and found a pekingese wandering around the road. We've put ads out, called places, etc and no one has claimed him. He was bathed recently and has clean ears and teeth so we know someone took care of him recently. I wish we could keep him but our bigger dogs can't stand him and I don't want him hurt. We've tried acclimating them together and nothing has worked. Hopefully a friend of mine may have a lead on a good home. Here is his picture:
