Eils and her husband Matt arrive at Fitzpatrick Referrals with their fox red Labrador puppy, Oscar. He's only six months old but is already suffering from rapidly worsening elbow disease which Professor Noel Fitzpatrick says is as bad as it gets in a dog this young. Eils is a vicar in Chertsey, and is pregnant with her first, and Matt's third, child. Noel proposes a two-stage solution for Oscar; to balance out the stress on his elbows by fitting custom made plates to both front legs, and injecting stem cells to help the healing process. It will be a complex operation.
