Dr. Pol challenges Charles to take part in the local Special Olympics charity event, the Polar Plunge, where participants dive into an icy lake in the height of winter.Then, Dr. Pol races to a farm call to check on a horse that's showing irregular symptoms. Meanwhile, Dr. Brenda discovers a cow is having respiratory issues and has twisted its stomach. Finally, Dr. Pol must race out on an emergency farm call to young racehorse who has severely wounded his leg, jeopardizing his racing career.

After successfully handling a cow with a twisted stomach, a rabbit with overgrown teeth and a complicated foal delivery, Dr. and Mrs. Pol head off to their much needed vacation. Taking care of his patients is Dr. Brenda, who tends to Debo, a rambunctious escape artist dog who has broken his foot in four places. She also aids a cow that may have slipped on ice and a cat with a toy in its intestines. Eager to help, Charles goes on a farm call with Dr. Brenda to check on a baby goat with pneumonia.

Roses are red, violets are blue, when animals go crazy, Dr. Pol knows what to do. For Dr. Pol, Valentine's Day means flipping a cow upside down to fix his stomach, de-worming a champion goose, and curing the relentless cough of Zev, the Siberian Huskie. Now, that's love. Inspired by Zev the huskie, Charles takes a shot at driving a sled dog team, but realizes that mushing isn't as easy as it seems. Meanwhile, Dr. Brenda dehorns a group of loud, but loveable pygmy goat babies.

As winter drags on Charles, Dr. Pol and the rest of clinic staff brave the frigid temperatures to keep animals healthy in the clinic and on the farm. The first stop is an organic farm where the owner recently lost two calves to a mysterious infection. Across town, Dr. Brenda is called out to visit a 10-month-old horse who has cut his leg badly on a rusty trailer. Later, Dr. Pol and Charles investigate two bizarre cases, both involving birth defects at the opposite ends of two young calves!

It is birthing season in Michigan, which means Dr. Pol and his clinic staff have their hands full. After receiving an emergency calving call, Dr. Pol and Charles discover that a heifer is already in labor -- but is still out in the pasture. So before he can help her, they'll have to catch her! Meanwhile, Dr. Brenda gets an urgent call about a few sick piglets that were recently purchased for a 4-H project, and she must stop this potential pneumonia epidemic before it spreads even further.

After a long, cold winter, the animals of Isabella County are getting testy. Dr. Pol and Charles head out on a farm call to treat an angry bull with a deadly case of bloat. Dr. Pol must act quickly, or the bloat could block the bull's diaphragm and lead to death. Back at the clinic, a cat injured while birthing kittens inspires Charles to volunteer at HATS, the Humane Animal Treatment Society, whose goal is to keep the animal population in check by way of spaying and neutering animals.

From cows and pigs to goats and pugs, celebrate some of Dr. Pol's greatest moments caught on camera. For over thirty years Dr. Pol has played an integral part in the health and welfare of both the people and pets across Michigan. His skills and dedication warm the hearts and minds of those lucky enough to call him their vet.

It's the best of the seasons at the Pol clinic -- springtime! Some of our most memorable moments of Dr. Pol and his team caught in a tornado, flooding rains, and strange happenings because of the full moon. They weather the storm of non-stop emergency calls from stalled cow births to animals with unusual birth defects. The springtime fun continues with cute baby animals preparing for 4-H competition and a ‘never seen before' case with Bill O'Reilly, the baby turkey.

Dr. Brenda tries to save a calf with a dislocated hip. Dr. Pol helps a hedgehog and a retired stallion and then judges a chili-cook off.

Dr. Brenda's 21-years working at the clinic is taken a look at. A horse receives help with weight management whilst a dog with a stomach wound is helped.

This fall, love is in the air at Pol Clinic as Charles plans a surprise anniversary getaway for his parents. But the Pols aren't giving just their marriage some TLC; there are sick animals across central Michigan that need Dr. Pol before he can get out of town and celebrate 46 years of marriage with Diane. First up is a bellowing, bloated calf with a problem much worse than a bellyache. Meanwhile at the clinic, Dr. Brenda is dealing with a snarly dog that has a gnarly hot spot on his cheek. Still, every so often a client comes in that stops everyone in their tracks. Today it's a beloved family cat suffering from a severe gunshot wound. From dachshunds to Rottweilers, sore husky pups, and to an abandoned pit bull.

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?

Dr. Pol may be from the Netherlands, but there's no question his home is Michigan - as a vet or a church member, or a high school football fan, Dr. Pol and his family are very much a part of the Isabella County community. In honor of his dedication, Dr. Pol is surprised with an award in recognition of his work with 4H. But he has little time to celebrate before he's off to help Marshall Farms' castrate some of the newest members of their cattle herd while also working to curb a potentially disastrous pink eye outbreak at Finnerty Farms.

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.

This Thanksgiving the birds are calling the shots at Pol Veterinary Services when Charles adopts three turkeys that are on the run. Then when Gail and Lynn Wernette find a pair of wandering Great Danes near their home, they bring them to the clinic. Thin and in poor health, these dogs are in need of some serious TLC, but Dr. Pol and Diane have a full house. The hunt is on for homes for these gentle giants. Later, it's all hands on deck when Capone, a horse with a nasty cut on its hoof, arrives in the clinic parking lot. It's an uphill battle as Dr. Pol wrestles with Capone, and calls for help from his owners to get the horse treated. It wouldn't be Thanksgiving without a meal shared with family and friends and everyone from the clinic gather for a traditional Amish Thanksgiving meal, taking a break from the business of work to enjoy one another's company.

Twas the week before Christmas and all through the farms, Dr. Pol is still working inside the red barns! It's beginning to look at lot like Christmas in Michigan as Dr. Pol heads to John Jourdain's for his first farm call of the day. Without a head chute, the set-up for these castrations is less than ideal - but nothing Doc Pol can't handle. It's clear these calves aren't willing to surrender without a fight. Meanwhile, Dr. Brenda races out to Rooftop Landing, where a reindeer named Ole is aching for a chance to pull Santa's sleigh. December ‘tis also the season when reindeers breed, leaving this buck cruising for a mate, and on his feet almost all day long. This wouldn't be a problem if he didn't have a massive hoof abscess growing on his back right hoof. Will Dr. Brenda be able to get Ole's hoof healed up in time to join the reindeer games? The end of the week finds the Pols in the mood for some holiday cheer. With Dr. Pol and Diane as Grand Marshalls of the Farwell Lights Parade and Charles volunteering as Santa's helper elf - the family can finally celebrate the Christmas season together.

It's a full day for the vets when Dr. Pol wrangles a foursome of gutsy cows that refuse their pregnancy checks and Dr. Brenda deals with an after-hours emergency when Sisco the horse is down with colic. The two vets are always ready for action, but with the clinic understaffed and Dr. Sandra preparing to leave the practice, life at the Pol Clinic somehow found a way to get crazier.

Halloween-themed episode in which Dr. Pol tends to the needs of a variety of animals. Included: cows; sugar gliders; horses.

Horses are driving Dr. Pol wild as he works to fix chunky runny noses, gruesome gashes and even penile problems. He’s always up to the challenge, but it’s a horse of a different color when Dr. Pol is asked to deliver a commencement address to the entire graduating class of Central Michigan University.

Vets, calves and cats are all having a hard time after getting the cold shoulder from Jack Frost this winter. Farmers, livestock and pets work to adapt while Dr. Pol stays warm the only way he knows how — by keeping busy.

The Pol Clinic vets are up to their coverall collars in clients and the new vet, Dr. Emily, can’t start soon enough as Dr. Pol juggles cases that send him out to help a horse combating colic, a rabbit that can’t hop to it, and a working dog named Stitches, with possible head trauma.

The animals of Isabella County are getting antsy after such a long winter and they’re up to more trouble than usual.

Dr. Pol certainly has a lot on his plate when a pit-bull is in for emergency surgery, a pair of pups run into a prickly porcupine, and Smoke the pet pig, is attacked; but Charles may have bitten off more than he can chew when he decides to enter the annual pancake eating contest.

Popeye the therapy rabbit comes into Pol Clinic with overgrown teeth but leaves with a couple of dates when his owner, Jodi, of nearby Hopewell Therapeutic Ranch persuades Dr. Pol to donate dinner with himself and Diane for her organization’s auction fundraiser!

A pup with eye problems, a bird with a busted beak, and a trio of possibly pregnant alpacas start the day, but emergency after emergency keeps the entire clinic hopping well into the night on one frantic Friday.
