Festive edition of the documentary following the work of Professor Noel Fitzpatrick and his team. Charity worker Kerry brings in Maxi, a three-year old rescue greyhound with severely damaged front legs. Noel's dog Keira is rushed into the practice with sickness and diarrhoea. The team also treats River, a Border terrier puppy who has fractured both back legs, and Noel makes a surprise visit home to Ireland.
