Britain faces an epidemic of dog obesity. As many as half of all dogs in the UK may be fat. Using surveillance filming and cutting-edge technology, and working with some of the world's leading experts, Dogs: Their Secret Lives discovers why our dogs are getting fatter and investigates what can be done to help them.
Following in the paw steps of three fat pooches - Chancer the Cavalier King Charles spaniel, Molly the bulldog and Cassie the Labrador - the programme reveals how dogs can manipulate us into feeding them and how weight problems can lead to far more serious health issues.
Mark Evans explores the challenges facing the 21st-century dog owner and finds out if a scientific approach to food and exercise could help our dogs shed the pounds.
