"Maybe I'm not the hero type. But I can dream. Sometimes I dream I'm a rescue dog, saving a child lost in the woods. Or a guide dog, helping a person who cannot see. Or a police dog, tracking sneaky robbers. But when I wake up, I must face the truth. It's mostly big dogs who do those jobs. And I'm just Barnaby, a small mutt living in an animal shelter." Barnaby has big dreams, but he finds his true calling when he's adopted into a loving home and becomes a bedbug-sniffing dog--helping to find hidden bedbugs in hotels, on airplanes, in movie theaters, and even in people's homes!
