Old Dog Cora & the Christmas Tree By Consie Powell. Cora is a huge Newfoundland dog with a great sense of responsibility and pride. For years it's always been her job to drag the family Christmas tree home through the deep snow. This year her family thinks she's too old to handle the job so they hitch the young dogs to the sled. How can this happen! Trying to reach the front of the sled she tangles the harnesses, making Pa angry. Now Cora is is completely confused. But, being a clever old dog, she takes a shortcut through the woods, emerges on the trail ahead of the team, and joyfully leads the family home. Her people realize how they've hurt her feelings and promise to let Cora wear her harness from now on. Powell wrote and illustrated this happy story, based on events in her own dogs' lives. hardcover.
