Olive the Other Raindeer

A movie about a dog named Olive who one day comes home from the store, only to find her owner putting away the Christmas decorations, saying that "Christmas is canceled this year." because Santa can't fly his sleigh because Blitzen is hurt and can't fly. On the radio, Santa says he's hoping to depend on "all of the other raindeer", which Olive mistakes for him saying "Olive the other raindeer". So she goes to the North Pole, gets chased around by a crazy mailman, befriends a penguin, and eventually saves the day.
