Dexter after

Finishing weight: 44.3 lbs

Total weight lost: 3.9 lbs (8 percent)

Waist decrease: 4.3 inches

"I have enjoyed taking part in the competition and although Dexter's not lost a huge amount of weight, he seems like a totally different dog. He's got a much higher exercise tolerance than he did before and that's great when we're going on walks," his owner said.
