On the Hawaiian island of Kauai, people in need of medical care for their pets often turn to Dr. Scott Sims. The owner of Pegasus Veterinary Clinic, located in his Kilauea home, Dr. Sims and assistants Dia and Ella keep busy treating a wide variety of domestic and wild animals. He makes "house" calls, too -- on beaches and mountainsides, in the water and jungle -- traversing wild, rural and oceanic Kauai topography. "Aloha Vet" profiles a man whose phone is rarely silent. With a heart of gold, Dr. Sims works long hours helping animals that walk, crawl, fly and swim.

In the varied forms of veterinary medicine, Dr. Susan Kelleher's practice may be one of the more unusual. Known as Dr. K, she runs South Florida's Broward Avian and Exotics Animal Hospital, and this series follows the staff as it cares for rabbits, ferrets, foxes, fish, birds, reptiles, marsupials, and even primates. As do some other vets, Kelleher thinks domesticating wild animals like monkeys is a bad idea, but that feeling doesn't interfere with her taking care of them: "If it will fit through the door, I'll treat it," she says.

Making house calls in the far reaches of Northern Canada is a daunting task in the least, considering the houses may be separated by hundreds of miles. That challenge doesn't stop Dr. Michelle Oakley from performing her many duties as a veterinarian in one of the most rugged environments on Earth. In addition to running an animal clinic out of her home in Haines Junction, Yukon -- where she lives with husband Shane and their three daughters -- Dr. Oakley also operates a satellite clinic 150 miles away and is the on-call vet for the Yukon Wildlife Preserve, which is about 100 miles from Haines Junction. She also makes house calls, sometimes driving for long stretches through desolate wilderness to check on a patient. This series documents how Dr. Oakley juggles being a full-time vet, wife and mom, and does so with a sense of humor and devotion.

Dr. Jan Pol has been a practicing veterinarian for more than half his life. In 1981 he and his wife, Diane, opened a vet business out of their home, and over the years it has grown to service more than 19,000 clients. Set in Central Michigan's farm country, this reality series follows the work done at Pol Veterinary Services. Specializing in large farm animals, Dr. Pol treats horses, pigs, cows, sheep, alpacas, goats, chickens and even an occasional reindeer. The program also features Dr. Brenda Grettenberger, who has worked with Dr. Pol since 1992.
