In this second book in the series, Roo and Wallace are still best friends who love to take walks and play in the park. It seems wherever they go they come across dogs with a variety of talents: show dogs, service dogs, and dogs performing tricks of all kinds. Roo wishes Wallace had skills, but loves him just the same. When they come across a man throwing a Frisbee to his dog, however, something amazing happens. The rest, as they say, is history.
