The chubby canine ballooned to 7st 2lb by gorging on toast, biscuits and a nightly bowl of his favourite Weetabix.

After being re-homed the five-year-old was put on a diet and exercise programme by owner Sarah James and lost 22lb, nearly a quarter of his body weight.

She enrolled him in her local Pet Fit Club, run by the People’s Dispensary for Sick Animals.
