Two perennial favorites — canines and heavy machinery — come together in a charming wordless book sure to please readers of all ages.Dog likes to ride along while his human companion works the big excavator at the construction site. But today, when they stop at the snack bar for something to eat, Dog’s little puppy friend goes missing. Luckily, Dog has a brave and ingenious idea for coming to the rescue — with the help of the excavator, of course! Incorporating bright yellow accents, Kate Prendergast’s wonderfully detailed pencil drawings tell a satisfying story of a loyal, resourceful, and clever pup.
