I think the narrator; a veterinary surgeon, seems to be a practical and tactful person. He knows how to deal with people. He adjusts himself well to the circumstances. He immediately understands Tricki’* problem. Tricki doesn't suffer from any sort of illness. The main cause of his illness is overfeeding. He takes the dog to his surgery. There the doctor keeps him on water diet and makes him physically active and treats without any medicine. The dog gets well under his supervision and natural environment of surgery.
