Ten-year-old Oscar weighed seven-and-a-half stone before taking part in UK-wide Pet Fit Club competition.

The porky pooch from Hamilton in Lanarkshire had piled on the pounds after munching on sausages, roast chicken and creamy pasta.

But after a health scare his owners signed him up for the 100-day diet competition, run by veterinary charity the People's Dispensary for Sick Animals (PDSA).

A drastic change in diet and a rigorous exercise regime followed.
Oscar, who was 32 per cent overweight, now weighs in at a healthier six stone.

Owner Louise Critcher said: "We were always under the impression that Labs were big dogs and we didn't think we were doing anything wrong by giving him treats.

"We used to feed him everything and anything. But then he collapsed and we thought he might have had a stroke. It turned out he had arthritis, but the vet recommended he go on the Pet Fit Club."

Oscar was put on a diet of dried food and water.

Mrs Critcher, 53, and her husband Gordon also started taking him on twice daily walks. Their pet's progress was monitored by weigh-ins every fortnight.

"At the beginning Oscar didn't take to the diet and used to look at us, as if to say 'is that it?'," Mrs Critcher added. "But he soon got used to it. Now he is a totally different dog."
