Can Cesar improve Troy's good behavior and keep him out of solitary confinement?

Also in this episode: Kim and Joel Givens bought Rat Terrier Roxy from a breeder when she was just a puppy. They wanted a calm dog that would get along with the children they planned to have.

Now, when two-year-old Roxy encounters a dog, she growls and cowers until the dog leaves. Roxy is so timid that when a guest comes to the house, or a sudden noise disturbs her, she pees on the floor. Kim wants to walk with the newest addition to her "pack," her two-month-old baby named Brennan, but Roxy seems terrified of the stroller. Roxy isn't getting all of the exercise she needs, and her tinkling problem is escalating. The Givens call in Cesar to help clean up Roxy's uncontrollable urination problem.
