The poor condition of Tricki, the pet dog in James Herriot’s story "A Triumph of Surgery", was mainly due to Mrs. Pumphrey, his overindulgent mistress.
Step 1: Mrs. Pumphrey’s Overfeeding.
Mrs. Pumphrey loved Tricki excessively and treated him almost like a human child. Out of her affection, she constantly fed him rich and fatty foods, including cakes, chocolates, and even wine at times.
Step 2: Lack of Exercise.
Along with overfeeding, Mrs. Pumphrey never ensured that Tricki exercised properly. His lack of physical activity made him lethargic, obese, and unhealthy.
Step 3: Medical Consequences.
Due to this lifestyle, Tricki became weak, listless, and suffered from various health problems. The narrator, Dr. Herriot, observed that Tricki’s illness was not natural but a direct result of Mrs. Pumphrey’s pampering.
Step 4: Conclusion.
Thus, Mrs. Pumphrey was directly responsible for Tricki’s poor condition, as her misguided love and pampering harmed his health.
