Call the vet that examined him, leave a message for him to call you back when he has a minute (today/asap)
He may need sub-q fluids again, until he starts eating/drinking on his own.
There are no veterinarians here, and even if there were, they could not advise you appropriately as they have not examined your dog. He may be dehydrated, you may have to go to the emergency vet. Start calling around, and give us an update.
