Bee, William. Digger Dog. illus. by Cecilia Johansson. 36p. Candlewick/Nosy Crow. Apr. 2014. Tr $14.99. ISBN 9780763661625. LC 2013943108. PreS-K–Aptly named Digger Dog sniffs out a bone and with catchy, repetitive phrases, uses increasingly larger digging tools and vehicles to break the hard ground and retrieve it. Digger Dog and his animal friends, wearing hard hats and using construction equipment, are set against polka-dotted grounds; they stand out nicely in the mixed-media cartoon illustrations. Though the dirt is not all that dirty, with circles in shades of peach and pink over brown, the effect is engaging as readers eventually see much more of it as the fold-out pages enlarge to accommodate “the biggest digger in the whole world” and then reveal that the bone Digger Dog finally uncovers is only the (finger)tip of the iceberg. A fossilized dinosaur skeleton still lies undiscovered, making a trifecta of kid appeal: dogs, digging, and dinosaurs.–Joanna K. Fabicon, Los Angeles Public Library
