Peter rushes to help a heavily pregnant cow who ‘isn't getting on with it' and, as she's expecting twins, which isn't common for cows, farmer Will is worried that neither calf will survive. Julian meets a ‘champion ferret', who's struggling with a badly infected swollen foot. Shona heads to see an old horse who is suffering with sore eyes: Barney has been by his owner Rachel's side for 24 years and she's desperate for him to be out of pain. Peter joins Matt at Jake Ratcliffe's animal sanctuary, where Leonard the miniature donkey needs taking in hand — he's been trying his luck with the bigger boys and his stablemate Catherine. Meanwhile, at the practice in Wetherby, new vet Ed has brought some fresh ideas with him, including dog acupuncture. And Julian's keen to try it for himself!
