Missing Dog. Please Help.

I arrived at work today and was given the sad news that one of our long time customers lost their dog after leaving the store (PetSmart) with him Tuesday evening and he's been missing ever since. The owner searched the area (Winchester and Hacks Cross) till 2am with no luck. His name is Puppers and he's microchipped. If anyone has found him, please bring him to the nearest vet or the Winchester PetSmart so he can be returned to his family. They've been searching for him and want nothing more than for him to come home.
