Hill's Pet Nutrition and NBC's "The Biggest Loser" host, Alison Sweeney, recently kicked-off the Million Pound Pledge, a program for pet owners to help their cats and dogs lose weight.

Pet owners who participate in the Million Pound Pledge will have access to a support system that includes two live video chat sessions with Sweeney on the Science Diet Facebook page, cat and dog weight loss tips, interactive body condition scoring to show the proper body shape of a cat or dog, rebates for Hill's Science Diet and Hill's Prescription Diet weight management foods, and more. Pet owners can also go online through March 30 and enter for a chance to meet Sweeney at "The Biggest Loser" live finale in May.

"Living a healthy lifestyle is important for my family and that includes my dog," said Alison Sweeney. "One out of every two pets is overweight, and my dog Winky was one of them. I started using Science Diet pet foods to help Winky lose weight and now I want to share my personal experience to inspire owners across America so they too can achieve the same success."
