Dr. Pol checks on a seemingly crazy cow and examines matching skin infections on a goat and pig.

Dr. Pol castrates feisty mini-horse, Mateo and tends to Jezebel a cow in distress and unable to birth her calf.

Dr. Pol and team are busy treating a very ill ox, a partly skinned dog, and a castration gone awry.

The first signs of summer are gradually creeping across central Michigan and Pol Veterinary Services is in full swing. Dr. Pol and Charles head to Gross Dairy Farm for an emergency call to help a feisty cow with a twisted stomach and a foul stench. Back at the clinic, Dr. Pol examines Ginger the goat and suspects it might have polio. Dr. Brenda receives an emergency farm call of her own -- a new heifer at Delbert Garrett's farm has a prolapsed uterus and is still straining post-labor.

The summer season is in high gear at the clinic as life-and-death situations stream in. Dr. Pol and Charles visit Stough Farms and Farmer Bill is one happy camper when he finds out that two-thirds of his cows are pregnant! At the clinic, Dr. Sandra examines a goat that gave birth the previous night. Its concerned owners suspect there may still be another baby inside. Meanwhile, Dr. Pol is across town at the Mogg's, tending to a pig that is suffering violent seizures.

Father's Day is just around the corner and amidst the typical onslaught of clinic cases and farm calls; Charles makes arrangements for a one of a kind father-son camping trip.

The tables turn as the Pol family pets go under the knife, and the clinic hustles to keep up with an onslaught of the puppies, kittens and calves, oh my.

Dr. Pol is almost as good on the road as he is in the operating room, so when he is given the opportunity to get in the driver's seat of a real racecar, this local veterinarian trades in his coveralls and stethoscope for a jumpsuit and helmet.

The fair's in town and Dr. Pol is busier than ever making sure his clients have healthy cows, sheep and pigs to show; while Charles' friend Dr. Jill pays a visit and shadows some of the farm calls.

Charles upgrades the computer system at the clinic, but training is cut short due to an emergency call for a sick baby horse. Also a bull runs away with a cow, while the other bull is neutered; an unsteady dog; a grumpy gator.
