A group of vet students are spending a week at the RSPCA, learning all about the types of work that goes on. They are full of enthusiasm, and Dr Joe is run off his feet answering all their questions. Cassie and Ben decide to organise a dog-washing fundraiser for the RSPCA and enlist the help of the student vets. One of the quieter students, Lauren, is able to prove that her skills extend beyond dog washing by helping with an emergency four-legged patient.
