S4·E6 Wonder Horse

Father's Day is around the corner and Charles is busy scheduling a unique father-son camping trip. Dr. Pol and Dr. Brenda see a mountain of cases at the clinic. First is a wild cow with an injured hoof. The team works to find the cause of the pain and heal the frantic cow without landing themselves with an injury of their own. Next to be seen is poor Chubbs, a playful black lab suffering a mystery illness. Can Dr. Pol solve this puzzling case so Chubbs can go back to his old, happy self?
