Meet the underdogs who overcame significant obstacles to become one of the world's top dog-sledding teams

In the mountains of Utah, the Rancho Luna Lobos race team is gearing up for their next competition as one of the top-ranked dog sled teams in the world. 

Each of the all-star canines is an underdog who has overcome significant challenges to reach their winning status. Most were abandoned or abused before being rescued by Fernando and Dana Ramirez, who helped them find new footing in life. 

The couple and their five children foster nearly 100 dogs on the 55-acre ranch, giving the pups a second chance at life and love. Fernando Ramirez began racing at just 8 years old alongside his rescue dog named Yellow, and sees his current life as an extension of those early years.
