Lobo is a tiny Chihuahua with a big dream—to join a wolf pack. When Lobo’s owner takes her pets on vacation to Yellowstone National Park, Lobo thinks he’ll finally have the opportunity to find his wolf-brothers. But he doesn’t count on a strict park rule that will keep him on a leash! With the help of his endearingly quirky family—a smart Spanish-speaking parrot named Glory and a wisecracking white rat named Heckles—Lobo finally slips his leash and gets a chance to run with the wolves. But is the wild really where a feisty little five-pound pup belongs?
