Dog owner Louise brings her poorly westie Duffy to Boroughbridge where, assisted by his wife and colleague Anne, Julian Norton faces one of his most challenging surgeries. Elsewhere, Peter races to an emergency lambing. Farmer Phil's ewe is expecting triplets, but has been unable to deliver two of them due to complications. Peter has to administer mouth-to-mouth resuscitation once the lambs are born, but will it be enough?0

Peter Wright reflects on a much loved farming couple, Jean and Steve Green. They were married 40 years ago and are looking forward to their anniversary vow renewal. Jean is moved to tears when Julian arrives with an anniversary present. Finally, as the big day arrives, the couple prepare to walk down the aisle again

Julian gets the call that all vets fear - a young cow has had a baby and prolapsed her entire uterus. This is a rare and life-threatening situation that is difficult for both vet and animal. Peter meets Jemima, a little duck with a big attitude, then comes face to face with his old friend Snakee, a constipated corn snake whose problems have resurfaced.

Julian is treating a pregnant ewe in distress when another animal on the same farm goes into labour, producing twins - one of which is in breach. Peter tries to find out the cause of a black labrador's mysterious tumour, while Helen has a very unusual patient - a rhea that has damaged a wing during an overenthusiastic start to the mating season.

With his wife and fellow vet Anne, Julian Norton heads out to see old friend Jacki Barlow on her alpaca farm, where one of the residents has a large lump on its foot. Other patients include a Labrador with a taste for gardening gloves, a hermaphrodite dog and a bloated bull.

Peter rushes to an emergency lambing at Rolland Norris' farm. When he arrives, he realises a ewe has prolapsed while trying to give birth. He later meets a goat named Buddy, who has come to the practice in Thirsk to get the dreaded `snip'. It sounds simple, but Peter discovers that Buddy's anatomy is somewhat non-standard in this area, and he will need to operate to complete his task. At Boroughbridge, Julian looks after pampered pug Ffion, who has taken playtime a bit too far and badly broken his leg. Julian needs to screw a plate onto the bones to allow it to heal, but it's a tricky job.

Peter Wright is called out to help a 10-day-old calf that has been rejected by its other, while Julian Norton decides to perform a risky operation on semi-retired sheepdog Mick, who has a tumour wrapped around his spleen.

Julian Norton is called out to see a big bull with the largest abscess he has ever encountered. Julian has to lance and drain it, knowing he is about to unleash a waterfall of smelly, infected pus. Meanwhile Peter Wright is called to an emergency at Debbie's stables - her horse McCoy has a mysterious cut that won't heal.

Julian Norton and Peter Wright face long nights as they help two struggling animals give birth. Dudley the hedgehog is brought in with pneumonia, and Julian attends to school guinea pig, Betty.
