Owen has a dog-walking business, but no dog of his own -- until he meets Hubble. The strange brown mutt isn't from the neighborhood, or even the planet Earth!
Now Owen must help Hubble with his secret mission from space: preparing Earth dogs for a visit from their ancestral leader, the Greater Dane. She is coming from Sirius, the Dog Star, to inspect all Earthbound dogs. And Hubble knows she won't like what she sees!
Will Owen be able to save Earth's beloved furry companions from being recalled into space? And will he be able to make a new friend in the process?
