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.
