Marley the dog is often in trouble, but during the first snow of the season he amazes his family with his good behavior.

When Mommy decide to surprise Cassie with a newly painted bedroom, she is careful to put the dog Marley in the garage before she begins the task. But as soon as her back is turned, Marley ventures into the house "to help." By the time he's done, the messy dog is in need of a little help himself.

Cassie makes a model of the solar system using fruit to represent each planet. When her daddy hangs the model in the dining room, Cassie's dog Marley thinks the solar system looks like fine dining indeed. Now Cassie has no project for school, but Marley thinks he can help.

Marley barks all day long, but when something important happens, he is worried his family will not pay attention to his warning.
