"Ana Ramos may not have a dog of her own, but she does get to walk her neighbor's adorable pug, Osito. One day, at the park, Osito befriends another pug, whose owner happens to be a cute boy named Calvin. When Calvin assumes that Osito belongs to Ana, she doesn't correct him. No big deal, right? Ana doesn't realize the trouble she has unleashed until Calvin shows up at her school. Calvin suggests setting up playdates for the two pugs, and Ana can't bring herself to admit that Osito isn't hers. In fact, her fibs keep multiplying! Will Ana fess up and figure out how she feels about Calvin before her white lies catch up to her?"--Provided by publisher.
