In renowned Chilean American author Allende's picture-book debut, a benevolent dog teaches a young boy a new trick.Perla, a small, scraggly shelter dog wearing a pearl necklace, possesses two so-called superpowers: the ability to "make anybody love me" and, even more impressive, given the dog's tiny stature, an enormous roar. The Rico family arrives at the animal shelter intending to adopt a formidable guard dog, but Perla manages to impress them with that immense roar and an assist from bespectacled young Nico Rico, whose insistence seals the deal. Perla proves vital to the Rico family-the canine even helps the family's lazy house cat, Lucy, banish mice. If only Perla could help Nico with his bullying woes at school! After Perla confronts a ferocious, dragonlike dog at the park one day, Nico asks the mighty mutt to "teach him the lion roar." Perla obliges-with hilarious results. Allende has crafted a winsome portrait of a miniature, magical dog whose droll commentary makes for a fab read-aloud, often elevating the central theme-finding the courage to stand up to one's bullies-above tepid familiarity. Rodríguez's vivid watercolor-and-ink artwork focuses on dynamic body movements and close-ups amid lush backdrops, pulling readers along in the fun from page to page. Nico and his dad have light tan skin, and his mom and teen sister read white.Paws up for this personable pooch. (Picture book. 4-8)
