The Humane Society has been requesting video submissions on stories about shelter animals and their owners changing each others’ lives. The story of Eric and Peety is the first of entries to launch the Mutual Rescue project.

In 2010, Eric weighed 340 pounds, had type 2 diabetes and high blood pressure. His doctor told him he’d be dead in five years if he didn’t change his sedentary lifestyle. At the suggestion of his nutritionist, Eric adopted Peety, a middle-aged, obese dog, from the Humane Society in Silicon Valley, Calif., and together they lost 165-plus pounds (Eric lost 140-plus pounds and is no longer a diabetic, and Peety lost 25 pounds from their daily walks). Eric also completed his first marathon in 2015.
