Peter has to deal with the most overgrown tortoise beak he has ever seen, and Julian treats a Vizsla puppy that has eaten a washing up-sponge for the second time. Meanwhile, David rushes out to a local farm where a ewe has suffered an unusual, life-threatening prolapse.

Peter heads up Sutton Bank for a lambing with a view. But there's no time to admire it because, when he arrives, farmers Craig and Liz have been struggling for a while.

Runtleigh has a painful, prolapsed eyeball, which is bulging, and the team rush her straight into surgery. Rohin meets Juliet — but it's no romantic tale. The young heifer has a large, unpleasant tumour like nothing he's never seen before. He needs to remove it and send it to the lab to find out if it's malignant. Meanwhile, Peter has a more pleasant cow conundrum — working out how many cows are pregnant thanks to big bull Cyril. And he shows graduate vet Hannah the ropes. Julian tries to conquer his fears when nurse Natalie brings in some of her exotic pets. Unlike his colleagues, he isn't keen on getting close to the snakes or the tarantula. And Matt's with some rhinos — the Leeds Rhinos rugby league team! His dad Alan played professionally for Leeds and Great Britain, and they take a trip to Headingley to watch a match, while comparing this most physical of sports to Matt tackling sheep and cows.

Peter rushes a pregnant husky into surgery, hoping he can deliver some live puppies, but he fears it might be too late to save the entire litter.

Matt responds to an urgent call from a 16-year-old farmer who is worried about his pregnant ewe, which has been struggling to give birth. Peter takes young vet Hannah to meet a huge bull called Cyril. He needs a pedicure, but doesn't seem too keen on the idea and when Peter and his apprentice are finally able to get started, the clock is ticking and nerves are jangling, because they know that the big fella might wake up at any moment.

A three-legged sheep called Star might be given a new lease on life with a prosthetic leg, but the rare procedure proves to be far from straightforward. Meanwhile, Julian meets Teddy, a very special 10-month-old dachshund and his owner Kerry, who believes Teddy saved her life when she went into cardiac arrest.

Matt rushes to a local cattle farm to help Tilly the cow give birth. Elsewhere, Mike and Rebecca have an amorous pony, who needs an appointment with Peter, and Julian operates on a young girl's poorly guinea pig, but he is shocked by what he finds.
