World-renowned dog behaviorist Cesar Millan is combating the global issues of canine abandonment and giving "unadoptable" dogs a second chance at life.

Following the wild success of his long-running series "Dog Whisperer," Millan's new show takes him to the beautiful country of Spain, where each week he transfers extreme canine cases to his new Dog Psychology Center in Miraflores - located just outside of Madrid. In each episode, three candidates from the U.K., Italy and the Netherlands compete for the chance to adopt one special pup, with their dog skills put to the test in a series of special Cesar Millan canine challenges.

Meanwhile, Millan employs his "exercise, discipline and attention" method to overcome hurdles with dogs that are particularly skittish or aggressive to painstakingly rehabilitate each one and prepare them for adoption.
