Dr. Pol is fielding farm calls all over Isabella County now that the spring birthing season is in full swing. Dr. Pol is ready to catch whatever curveball a cow throws his way, but when the local minor league baseball team asks him to throw the first pitch, it comes right out of left field. He may not be a baseball pro, but Dr. Pol knows how to play hardball, and after practicing with Charles, he’s going to show Michigan a first pitch to remember. But practice comes last when Dr. Pol still has so many farm calls to deal with first!

It's no secret that Dr. Pol has a need for speed; in his stable of unique cars, the stainless steel DMC DeLorean is one of his all-time favorites, but much like his patients this week – a prolapsed 4-H pig, a duck with a mangled web, and a cow with udder issues – this iconic car needs some TLC.

The Isabella County Fair is just around the corner – which means Dr. Pol, Dr. Emily and Dr. Brenda are busy treating fair animals, making sure they are in tiptop shape for competition. Dr. Pol and Charles start the day tending to a fair pig, whose future isn’t looking so fair after all. Will Dr. Pol be able to get this prolapsed show pig back in shape? Across town, Dr. Emily’s up to bat, with a cow named Toro – who’s abdominal hernia seems to be more than a hiccup on the road to winning the blue ribbon. Now it’s Dr. Brenda’s turn – there are two horn-y things on the heads of steers, Big Ron and Hannah, preventing them from getting fair-side.

The staff of Pol Vet Services has one head-scratcher after another, from the peculiar to the downright bizarre. With over 19,000 clients, it’s only a matter of time before the vets are presented with a unique case that they’ve never seen before. Dr. Pol leads the charge into uncharted territory. He devises a way to noninvasively remove penile carcinomas threatening a beloved horse, and advises a client on how to best treat her duck whose penis has prolapsed. Dr. Brenda also has her hands full with a herniated pig, and a beagle that has a brain-shaped vaginal polyp. Not to be outdone, Dr. Emily, the newest vet at PVS, completes her ‘first flip and stitch’ LDA treatment on a dairy cow, treats a tongue-twisted horse, and delivers a deformed calf with no anus. All in a days work at Pol Vet Services!

Runaways, adventurists, and escape artists—what’s gotten into these animals around town? First, Dr. Pol is called in to assess two runaway bulls who’ve shown up at Tom Knoll’s Farm. Across town, Dr. Emily is responding to a complicated emergency calving. It’s going to take some repositioning to get this calf out, and Dr. Emily has to hustle in order to save both the calf and mother. Later, at the clinic, Dr. Brenda is helping Miss Kitty who’s in with a problem that’s making her young owner squirm! Back at their home, Athena and Donar get together and finagle their way out of the house – is there any stopping them? Will Charles ever catch up to these great adventuring Danes? Between canine hijinks, bulls on the loose, and an attempted kitten getaway, the Pol’s sure have their hands full!

It’s another busy week for Dr. Pol both in the clinic and at home. Clients take matters into their own hands and our vets have a slew of do-it-yourself doctoring to repair. Dr. Brenda’s got her hands full devising a creative treatment plan for Cash, a hyperactive blue heeler puppy whose owners had no choice but to create a makeshift splint for his broken leg. Dr. Pol sees some crafty DIY treatment himself when a client uses super glue to mend a gashed lip after his pug, Buddy, got into a fight and lost. While Dr. Pol deals with Buddy, the stakes are high for a beloved hunting dog, Sadie, as Dr. Brenda corrects a homegrown suture procedure gone wrong. As if they’re not busy enough at the clinic, Dr. Pol, Diane and Charles embark on some ambitious home improvement projects at the lake house. There are no days off for the Pols … and that’s just the way Doc likes it.

From gimpy goats to belligerent bulls, families all around are relying on Pol Veterinary Service to take care of their animals this summer. The first patient of the day is a loveable family pup who got a little too close to some farming equipment. With a few stitches from Doc Pol, he'll be up to snuff and playing with his family in no time! Later, a young girl arrives with her dad and her cat, Princess. Curiosity got the best of this cat when she managed to get a fishhook stuck in her leg—will Doc be able to rescue this Princess in peril? Later in the week, it takes the whole team of doctors to help an injured goat named Willie. Willie seems to have twisted his neck but that may just be a sign of an even worse illness. All the while, Charles has been tending to his newest baby—a little peachick named Drogo. With the help of Dr. Pol, Charles is becoming more and more like his father, with a flock of his very own.

It's another busy week for Pol Veterinary Services. Across town, there's a stalled labor at McConnell Farms, which gets doubly complicated after the team realizes the mother is birthing twins. Every minute is critical, especially with a twin calving, so Dr. Emily calls Dr. Pol for a little lesson on his way to handle it. Back at the clinic, Marshall the pig arrives with his new family. Marshall's feisty as can be, and with a squeal to match. His owner, Kassie, hopes Dr. Pol can figure out what's causing this piglet's tantrums. Over at the Michigan Renaissance Festival, Dr. Pol takes a look at the hooves of a limping horse named Maverick, a jousting giant scheduled to compete at that day's tournament. Will Dr. Pol be able to help this stoic steed in time for the show?

It's Dr. Pol's birthday—but before the celebrations can begin, there's a bevy of cases for the Pol Veterinary staff. From colorful parrots to a sick zebra, Dr. Pol's hands are full with this week's exciting cases! The first call of the day is from Gary Smith. He needs Dr. Pol to perform pregnancy checks on a whopping 86 cows at his farm! With the fighting and kicking, it takes hours to get all these cows accounted for. But with a lot of help from his right-hand man Charles, Doc gets the job done and is on to the next. Back at the clinic, Dr. Brenda and Dr. Emily are both looking after some troubled pups. Little Annie has a severely fractured bone in her leg. Dr. Brenda has to weigh all the options and determine what's best for this still-growing pup. Meanwhile, young Ayasha wants to be a doctor when she grows up. When she arrives at PVS with her new puppy for a checkup, she wastes no time in teaming up with Dr. Emily to give her best friend a clean bill of health. At the end of a long day, the Pol family surprises Doc with a birthday dinner. For a man whose plate is always full, the night provides some well-deserved relaxation and celebration!

The leaves have changed and the first hints of winter appear in central Michigan. Dr. Pol and the PVS crew are still hard at work servicing the farms and small animal owners of Isabella County and the surrounding areas. Spitting llamas, a surly Scottish highlander, and a red heeler who had a run-in with a car are just a few of the surprises in store for these dedicated vets. As they zip through the unforgiving Michigan countryside in their trusty trucks, every day brings a new set of challenges—vehicle troubles included.
