David Melleney rushes home from a family holiday when his own dog is badly injured, while Julian Norton operates on a lovesick skunk called Pepe. Alongside handling an emergency lambing, Peter Wright helps nurture farming's next generation by working with an agriculture student.

The vets and nurses split into two teams for a festive fundraising challenge to support charities close to their hearts. Julian Norton, Matt Smith and Nurse Lucy take on the world's fastest zip line, hitting speeds of over 100mph, while dressed as reindeer, while Peter Wright recruits Shona Searson, Rohin Aojula and David Melleney for a Christmas horse ride. Peter and Julian also go head to head in a Christmas jumper design challenge, with the winning creation revealed on the catwalk during a charity extravaganza at Cannon Hall Farm.
