Meet Zena, a pit bull/chow mix whose extreme fear of the stove has forced her owners, who live outside of Phoenix, Ariz., to cook outside on a grill for the past year. Next, Cesar visits Major, a Rottweiler, and Nira, a German shepherd, who are battling for control of the house. Finally, meet Willie, a Jack Russell terrier who cant handle the death of his pack leader, the family cat named Jake.
