Japan is a paradise for pampered pets. There are dog manicure salons, dog spas, cat gourmet treats and many other ways to treat your furry friends. A trip to the nearest park will reveal plenty of owners walking dogs who are quite often dressed in fancy outfits. This means the Interpets event at Tokyo Big Sight on July 24 will likely be crowded, but it could also be entertaining, even if you don't own a pet.
