A formerly beefy Beagle has been crowned top dog after shedding a third of his body weight.
Luigi, from Newport, whose love of Sunday dinners saw him bulge to almost 5st, shaved eight inches off his waist in six months after being put through a rigorous workout regime by a fitness club for pets.
The five-year-old was awarded his title by animal charity PDSA's Pet Fit Club after reaching 3st 3lb - the perfect weight for his breed - after his huge appetite saw him balloon to almost 40% over his ideal weight and threatened his health.
Luigi's diet and exercise challenge included spending more time outside for walks and cutting out his intake of extra food and treats.
Owner, Perrie Eedy, said her dog's fitness regime also had a positive effect on herself and husband Matt Jordan.
His love of roast dinners was entirely my fault, I love them myself. As a treat I would give him a bit of carrot or some beef. I thought I was being kind.
But Luigi's weight-loss journey was not without hiccups
We got married earlier this year and put Luigi in a home boarding kennel for a few nights, but while he was there he managed to break into the locked utility room where the food was kept.
