Together Again: found!
We went for a walk tonight to see if maybe someone had seen him. A car was going very slowly and stopped to see if we were looking for a dog and if he was black. We said yes and he came running from behind the car! The people had fed him and gave him water for two days. We thanked them and brought him home! He is so tired he came in, drank a bowl of water, ate some food, and then looked like he became a rug on our floor. Lol! He didnt even want to go out right before bed to go to the bathroom.
