Nicki is a highly dog-aggressive Rottweiler who came from a horrible situation in a homeless camp. Kathleen Daniels and her son Donald rescued him and now want to get him past this aggressive behavior so that he can have the life he deserves. Cesar and his wife, Illusion, test Nicki with one of their dogs, and Nicki does quite well. They decide to evaluate him further by taking him to Cesar's Dog Psychology Center. Nicki's calm-submissive behavior away from Kathleen and Donald shows Cesar that they are not consistently demonstrating leadership. Nicki spends two weeks at the Dog Psychology Center learning to be part of a pack and being worked with daily. At the end of the 14 days, Cesar takes Nicki home, along with a few of his new doggie friends; Nicki has no trouble allowing them into his territory. (thetvdb.com)
