It's time for the Isabella County Fair, which culminates in the 4-H competition. Dr. Pol and his staff are busy tending to animals that need last minute checkups to make them eligible to compete. Dr. Pol, Charles and Dr. Sandra bounce back and forth between the fair and farm calls, while Dr. Brenda holds down the fort at the clinic to deliver a set of bulldog puppies. When Dr. Pol and Charles get in to a bidding war over a sheep at the fair, it's anybody's guess as to who will come out on top.
