Seaman and the Great Northern Adventure — Helen Moss

When a pack of senior dogs find themselves transported back in time―and turned into puppies!―they must make their way back home, helping real-life historical dogs along the way.

In this second adventure, Baxter, Trevor, Newton, Titch, and Maia―the time dogs!―find themselves transported through time and space to 1805 on the Missouri River. There, deep in the wilderness, the puppies must help Seaman, the dog of legendary explorers Lewis and Clark.
