Cesar works with a couple who are concerned that their daughter's pit bull, Luna, has become a menace to the family. He then works with a makeup artist and hairstylist whose Sheltie, Belle, barks constantly whenever she picks up a blow-dryer, curling iron, or other small appliance, preventing her from having clients come to her home.

Cesar helps a German shepherd, Ovechkin, who terrorizes a family and has them living like prisoners in their own home. Cesar confronts the aggressive dog and is attacked himself. He utilizes members of his own pack to make Ovechkin less territorial. Once Ovechkin is rehabilitated, Cesar reunites him with the owner but learns she is still too weak to control her dog.
