Dr. Pol and Dr. Brenda face another unpredictable week of diagnostics, treatments and surgeries. He visits a local breeder and frequent client to check on her limping horse, DooBee. Though DooBee isn't really a compliant patient, the doctor's tactics help him treat his old friend in no time flat. Across town, Dr. Brenda gets help from an Amish boy while treating his newborn foal. Charles and Dr. Pol deal with one of their most dangerous patients yet -- an angry cow separated from her calf.
