We all know dogs rock. They improve our lives in countless small ways every day—motivating us to be active and patient, making us laugh, helping us in work and play. Sometimes they go an extra mile, saving us from injury and even death. For three years, The Humane Society of the United States has celebrated these ubervaliant pups with the Dogs of Valor Awards. This year’s big winner was Kenai, a 14-year-old Bernese Mountain Dog mix in Colorado, who alerted family and friends to a life-threatening carbon monoxide leak. Runners-up foiled a violent home invasion and alerted a sleeping family to a house fire. Move over Lassie! Read their stories here.
