Horses are driving Dr. Pol wild as he works to fix chunky runny noses, gruesome gashes and even penile problems. He's always up to the challenge, but it's a horse of a different color when Dr. Pol is asked to deliver a commencement address to the entire graduating class of Central Michigan University.

The Pol Clinic vets are up to their coverall collars in clients and the new vet, Dr. Emily, can't start soon enough as Dr. Pol juggles cases that send him out to help a horse combating colic, a rabbit that can't hop to it, and a working dog named Stitches, with possible head trauma.
