The first priority of owning any dog is taking care of his health. Something as seemingly harmless as vomit can potentially be a life-threatening situation for your dog. If you don't know where to take your dog for aid, contact your local animal health center or local police department's non-emergency number. They will have a list of veterinarians and animal hospitals in the area. In many cases, veterinarians have limited hours, so if an issue comes up in the middle of the night, you may need to drive to an animal hospital for care.
