After working hard throughout her pregnancy, it's just about time for Dr. Emily's maternity leave – but not before Dr. Pol and crew treat a slew of young animals.

The gloomy weather doesn't stop the crew from taking on a range of unique cases, including testy bulls, coughing pigs and wobbly reindeer. Once their work is finished, Dr. Pol and Diane take a little trip to Holland, Michigan. Reminiscent of Dr. Pol's home country where the two once lived together, Jan and Diane enjoy a day holding hands and laughing over the bright tulips.
