Pluto is pressed into duty to deliver a sack of mail to a remote arctic outpost, helped along by a playful arctic rabbit.
Mail Dog
When a pilot has to turn back due to a severe storm, he drops the mail at a remote outpost where it can be delivered by dogsled. The falling mail pouch lands on Pluto, and he sets out to deliver it. He is continually delayed by a rabbit along the way, but in the end, the rabbit helps Pluto deliver the mail pouch.
