The animals have human characteristics and can communicate with each other but are limited in how they can communicate with their human owners. This adds humor and frames the story as the human owner of Sparky only appears at the beginning and end of the story. Notes at the end explain different places in London that Sparky explored. The facts are a good way to give some nonfiction facts in a fiction story. The illustrations should help the reader recognize Buckingham Palace and Big Ben and is a good intermediate chapter book series. Fans of some toilet-bowl humor will think Sparky's peeing at inappropriate times and puking on the floor funny. Can't tell you how many squirts I find in the library howling over books that have this specific type of tickle-your-bones humor. Or in this case it might tickle-their-magic-bone. Light, fun fare.
