Olive, the Other Reindeer by J. Otto Seibold & Vivian Walsh

This is a charming holiday tale about a little dog named Oliver, who after hearing the line of a song (All of the other reindeer....) thinks she must be a reindeer, not a dog. So Olive heads to the North Pole to help Santa and his reindeer deliver their presents to boys and girls all around the world. The other reindeer are a little confused by Olive, but soon learn to appreciate her special talents. This is an excellent Christmas story for toddlers and preschoolers alike.
