Cesar Millan is on a mission to find perfect homes for "unadoptable" dogs. Follow Cesar as he searches for a new Pack Leader for Rosie, who has been in and out of shelters and has developed some bad habits. She's lovable, despite her issues, but there's one problem: she's a Staffie! This breed has a bad rep in the U.K., but Cesar shows that it's not about the breed; it's about the human who handles the dog. He's determined to help Rosie overcome her bad habits and find her the home she deserves.
