Help! My Dog's As Fat As Me

Eight fat dogs and their equally overweight owners take on a joint diet and exercise regime in the ultimate weight loss contest. A springer spaniel, a Jack Russell and a bulldog compete in the grand final. After a weigh-off, one of the pairs is eliminated and the remaining two fight it out in the ultimate canine challenge - the Kennel Club's Dog Agility Course in London's Olympia. But Ricky and springer spaniel Henry suffer a setback when Henry pulls up lame.
