When a rescue dog is adopted and named Frankie, she thinks it's all too good to be true, in this book for readers 4 to 7. Upon arriving at her new home, Frankie discovers the "three B's" so adored by dogs: a ball, a bone, and a bed; in each case, however, these things already belong to the cranky canine Nico, who doesn't take kindly to this newcomer. Can the two dogs ever learn to share? In her text, the Geisel Honor- winning author-illustrator of Balland Treatmirrors the difficulties and anxieties of children adapting to new siblings, while her understated, digitally-colored pencil illustrations perfectly capture the emotions of the gawky pup and its tubby antagonist.
