Meet Moose, the biggest dog in the world. Moose lives in a traveling circus. One day he tells his closest friend, a cat named Big Yellow Face, he is tired of moving from town to town. Moose wants a house that is a real home.

Deuce and Diesel meet Moose at the circus and take him home to try and fit him into their small world.

Miss Dixie explains to Moose that it's not a house that makes a home. What truly makes a home is being with the ones who care about you, your family, and the memories you make with them.

Moose comes to realize that he's had a home all along with his friends in the circus who care about him.
