Doc Martin: Season 9, Episode 7

9 - 7: Single White Bevy

While at the surgery Angela comments on Buddy, the dog, not being himself. Buddy's condition worsens and Martin rushes him to Angela's surgery. He discovers Angela can barely see and diagnoses cat scratch fever. But her condition means she can't operate on Buddy, and that the Doc must carry out the surgery himself, under her guidance, to save the dog.
