While observing all the dogs in the park, Hazel realizes that first impressions are never the whole story of someone's personality. Hazel has things all figured out--she is one clever girl. So, when she encounters a snarling dog in the park, she knows that dog is mean . And as her walk continues, she identifies a sweet dog, a sad dog, a naughty dog, and many more. But then something happens that leads Hazel to experience all kinds of different reactions herself, and she takes a second look at the dogs. Soon she sees that dogs--and people!--are not just one thing. We're each our own special mix of all sorts of emotions and behaviors. We're all that --and more.

And what of the snarling dog? A surprise is in store for Hazel and the reader!.
