The Yorkshire Vet - Season 4

A badly injured llama has smashed his jaw and lost several teeth. The Greens have taken in a stray cat who needs a health check. New mother Butterfly's calving caused a potentially deadly prolapse. Ella is in agonising labour to birth her puppies.

Julian is called out to a desperately ill calf. Peter treats an elderly cat with severe constipation. Other patients include a young, wild stag trapped by its antlers, a dog with a dislocated leg, a postnatal cow and five noisy, young goats whose horn buds need removing.

Patients include a semi-feral cat named Pretty Tom, a ewe in labour, a lame doberman named Obi Wan, a sexually frisky young donkey and a hyperactive hamster.

Julian Norton has a large lump to remove from between a Highland cow's horns, then must find out why an event horse has broken out in lumps from head to hoof. Meanwhile, Peter helps a first-time mum deliver her lambs and treats a micro-pig who has outgrown his house and is under the weather.

Julian is called out to a poorly three-day-old calf who has collapsed, before turning his attention to Elsie - a piggy who needs a pedicure. And unlucky terrier Holly is brought into the surgery after falling off a bed and fracturing her leg in two places.

Julian races against time to save two alpacas, Peter treats two sheep with eye problems, two pet calves with suspected pneumonia and a cow in labour

Julian gets dragged around a barn by one-ton bull Merchant, and operates on police dog Thor. Peter helps a baby goat open its eyes and fixes a cat with loose teeth.

Peter tries to save the life of a cow whose uterus prolapsed while calving. Julian must remove the sharp and dangerous tusks from an unco-operative 300kg boar.

It's the last in the series as we bid goodbye to Skeldale, Julian and the rest of the team.
