The Pols are experiencing some unusual emergencies and the only explanation they can think of is the full moon. Dr. Pol and Charles head to a cattle farm to perform pregnancy checks. For the first time ever, all the cows they examine are pregnant! Back at the clinic, an X-ray of a dog hit by a motorcycle shows bruising, but no broken bones. Luckily, the dog is able to leave that day. Then Dr. Pol heads to treat a pig with a rectal prolapse - a dose of antibiotics will help alleviate discomfort.

Temperatures are blazing in Michigan and there are more farm calls than ever. The heat also brings more pregnancy checks and births, leading Dr. Pol and Charles to start their day by heading out to a stable to check the status of some horses. Meanwhile, Dr. Brenda heads to a ranch to vaccinate minihorses, but instead gets some screaming and kicking. By the time she's finished, Dr. Brenda is bruised and bleeding, but she never gives up when it comes to the health of their patients.
