Rescue dogs help save lives in Colorado flood zone

The families of nearly 200 people are anxiously waiting for word from their loved ones who remain unaccounted for after the deadly floods in Colorado.

Those raging waters have already taken the lives of six people and left more than 450 stranded for nearly a week with little food and water.

But help is on the way with one of the nation's largest air operations in nearly a decade.
