Martin Paterson from the Huddersfield animal hospital heads into war-torn Ukraine, travelling over 1000 miles in an ambulance loaded with medical supplies. And while he's briefly switched to helping people, he also visits a homeless animal shelter to see the effects the war is having on the country's pets. Back in Thirsk, Julian Norton's treating a rescue dog called Woody, who has a worrying tumour in a very delicate spot, which might make it tricky to remove. Peter Wright heads to visit his old farmer friend's sheep, who has a huge lump on her jaw. Matt Smith's patient at a local college is a duck with penis problems - and amputation might the only option. 

When Julian Norton's beloved Jack Russell Emmy is sick, it gives him an idea. While he can use his vet skills to help her, he calls on his good friend, popular animal artist Lucy Pittaway, to immortalise Emmy on canvas. Peter Wright deals with a life-threatening emergency at the practice, when a pet goat called Fred is unable to urinate because of a blockage. Fearing Fred's bladder may already be ruptured, the team head into theatre to try and save him.
