Mark's dog Wolfie is part malamute, part German shepherd, and all heart. Mark can hardly imagine life without his big, loving canine companion. But in 1969, the Vietnam War is still raging, and when Mark learns that the army needs scout dogs, he decides to send Wolfie. As his dad says, a smart dog like Wolfie could save a lot of soldiers--soldiers like Mark's brother, Danny. Besides, it seems like the patriotic thing to do. Inspired by real events, this is a heartbreaking story about sacrifice, loyalty, and the complex meanings of patriotism.
