Trouble DogTrouble Dog

"Tucker the dog never means to be trouble: he just loves to play. But at the animal shelter, every visitor says he's too much trouble -- until Laura. Laura thinks Tucker might just be right for a very special job. Could all his energy make him an amazing conservation dog? Laura trains Tucker to track down endangered flowers, Gila monsters, even grizzly bear poop. His first assignment is in Hawaii, searching for invasive snails hidden under leaves. Where will his nose lead him next? Based on the lives of two real conservation dogs, this tail-wagging adventure invites readers to join scientists -- and their canine colleagues -- as they work to save wildlife around the world."-- dust jacket flap.
