Poncho yearns for a little excitement in his life. Tired of sleeping on the couch next to his owner, this dog seeks adventure; he wants to hunt for bones in his backyard. He enlists his older brother, Chico, to help.
Together, Poncho and Chico dig and dig and dig until the hole is very deep. The two chihuahuas surprisingly find themselves in Alaska where they are introduced to a whole new world of the Iditarod and Siberian huskies. They learn what it’s like to pull a sled in the cold and the snow.
Exhausted, the dogs are glad when they return home to Mrs. Sunshine, but they can’t help but dream of their next exciting adventure.
