The narrator is a veterinary surgeon. He is a tactful person. He had known that Tricki was about to fall in trouble. He was sure about Tricki’s treatment and suggested for his hospitalization and to be kept under observation for a fortnight. He said Tricki would have to undergo surgery but instead let him mix with other dogs and did not pamper him. Tactfully, he treated Tricki with giving him less food and more exercise. He had a commonsense. He realised that there was no need for surgery for Tricki and the only treatment of his illness was to change his eating habits and give him more physical exercise.
