This week, the Pols go Dutch when a special visitor comes to town - Charles' uncle Jan is visiting from the Netherlands! Uncle Jan doesn't speak English and Charles is on a mission to learn enough Dutch to finally have a conversation with his uncle. Dr. Pol helps when he can, but he's got to stay focused on the job while dodging a feisty cow with a stinky foot problem and helping a down-cow taking a treatment that could kill it. Brooks, a puppy with a protruding hernia and Buddy, a Shih Tzu with a bulging eye who's seen better days, keep the clinic hopping until Uncle Jan is in Michigan. Will the conversation be lively or Charles find his attempts fall flat on Dutch ears?

The Pol Clinic is bursting at the seams with two-legged and four-legged traffic, and Dr. Pol and Diane are ready to expand. Cement mixers and cranes have the Pol clinic buzzing with anticipation for this latest addition. But on the road it's business as usual for the crew as Dr. Pol, Charles and Dr. Brenda tackle the problems of a feisty alpaca, a troubled twosome of dairy cows and a miniature donkey with a fungus problem on its feet.
