Rosie is a shy Jack Russell terrier who lives with George. She’s mostly happy with her predictable life but occasionally sees another dog and feels lonely. When George takes her to the dog park, she meets a big dog named Maurice and a small yippy dog named Fifi. Rosie is not sure she wants to interact with either one until a sudden emergency causes her to take action. The understated narrative is perfectly matched by mostly realistic watercolor paintings that tell the story in a comics format. Short declarative sentences broken up into nine brief chapters are full of humor that comes mostly from perfect comedic timing and textual restraint. The interactions of the three dogs—all so different from one another in breed and personality—is at once realistic and hilarious in the illustrations, which excel at communicating canine emotions through body postures. A book showing a tremendous respect for the intelligence of children is one that adults will enjoy reading and re-reading as much as children do, while many newly independent readers will enjoy the sophisticated humor. (Ages 3–7)
