Mrs. Pumphrey's overweight dog, Tricki, falls ill and is taken to the veterinary hospital. The veterinarian, Mr. Herriot, cares for Tricki and puts him on a diet, which leads to a fast recovery. Mrs. Pumphrey sends eggs, wine, and brandy to the hospital for Tricki, which Mr. Herriot consumes. Though Mr. Herriot enjoys the gifts, he decides to return the recovered Tricki to his anxious owner.
