What’s a boy to do when everyone has a dog but him? Why, ask for one, of course! But when mom refuses and points to the pet goldfish instead, the little protagonist attempts to make his case with both reason—a fish can’t play fetch, go for walks or wag its tail—and a little manipulation—unleashing his most “hypnotizing eyes” on her. Mom doesn’t take the bait: “if you can’t have what you want, you could try to want what you have.” Taking her advice to heart, the boy, with some patience and ingenuity, makes his aquatic pet a worthy canine substitute and finds real joy in his new “DOGfish.” Shields playfully introduces readers to nuanced emotions such as irritation, sorrow and bliss, deftly developing the characters of both boy and mother. Taylor’s digital illustrations, done in warm color harmonies, share the post-World War II–era optimism of the Little Golden Books. With clean, simplified graphics, expressive characters and friendly spherical shapes, the illustrations do much to enhance the text’s appeal. An agreeable choice for those who know the will of the canine-obsessed youngster. (Picture book. 3-7)
