Jorjan Powers at the Bergin University of Canine Studies in Santa Rosa, Calif., says studying here is not just about a love of dogs -- but it sure helps. Degrees on offer at the service-dog school, the only one of its kind in the world, include an associate science, masters in science, and bachelors in dog studies, and courses on social therapy, scent detection and puppy training. The college breeds its own golden and labrador retrievers and also works with local breeders to raise four litters of assistance dogs annually. Students will attend the college on site for two or three-week sessions then complete the course online. She says prospective students must be able to speak English, and students from as far afield as South Korea, Japan and Taiwan all have graduated from the program. Saying that the school's primary mission is "helping dogs help people," she adds: "People come here for serious study: how to run a business, a kennel, or fundraising."
