When traveling with dogs, one thing is certain. Poop happens. For those times when you forgot to pack your poop bags and need to find the closest store in an unfamiliar town, or even worse, when you need to find an emergency veterinarian open at 4:00am in the morning, turn to our directory of pet businesses for information on our favorite pet stores, veterinarians, doggie daycare facilities, sitters, groomers, trainers, and other pet professionals.
