The Isabella County Fair is just around the corner - which means Dr. Pol, Dr. Emily and Dr. Brenda are busy treating fair animals, making sure they are in tiptop shape for competition. Dr. Pol and Charles start the day tending to a fair pig, whose future isn't looking so fair after all. Will Dr. Pol be able to get this prolapsed show pig back in shape? Across town, Dr. Emily's up to bat, with a cow named Toro - who's abdominal hernia seems to be more than a hiccup on the road to winning the blue ribbon. Now it's Dr. Brenda's turn - there are two horn-y things on the heads of steers, Big Ron and Hannah, preventing them from getting fair-side. When the gates open and the animals come rolling in - Doc Pol's the man the Isabella County Fair looks to, to make sure all of the 4H animals are healthy and ready to show. But just because Dr. Pol works at the fair, doesn't mean he can't have a little fun at the fair too!
