A dalmatian puppy called Reg is rushed into the hospital after eating a mystery object that's become stuck in his intestines. A scan shows that there's only one way to get it out, and that's to operate. Rupert, a King Charles spaniel, has an appointment to see the experts in the neurology department to try to get to the bottom of his headaches, which can be common in this breed. Becky, his foster carer, would also like to find out what she can do to cure his life-threatening lung infections, and so clinical director Ben looks into his case. In the oncology department, the team are seeing Alexandria, a cat who is undergoing chemotherapy. They hope this will be her last chemo round and give her some well-deserved treats.
