With no appointment necessary, Gateway is a nonprofit animal hospital that defrays costs by cutting overhead. Those savings are passed on to its customers, making its services affordable to low-income pet owners. But with the best veterinarians in town, it's the animal hospital of choice for more affluent pet owners as well. One of the veterinarians, Dr. Bob, is known for having a good petside manner and ability to translate medical terms into layman's language. He'll even take the time to help you identify the genetic makeup of your mixed-breed dog. How cool is that?
