Mixed up Chow

Deborah Carmichael, Damon Carr, and Deborah's daughter, Catherine, live with Stewart, a Chow/retriever mix who barks incessantly, and from the families' description, sounds like she has multiple personalities. As always, Cesar starts by teaching them to master the walk. As they are out walking, Cesar introduces three elements that usually cause Stewart great distress: other dogs, children and mail carriers. Cesar's wife and sons, Illusion, Andre and Calvin, and one of their dogs are there to help him. The mail carrier for their street, despite her visible discomfort, also stops and allows Cesar to work with Stewart near her. He tells them how to tactfully prevent people from just walking up and attempting to touch Stewart since she dislikes it. To stop her from the door barking that is so common and annoying, Cesar shows them to put her on leash and correct her when she barks.



Hose Dog

Johnny and Christine Johnson, have Buddy, a Beagle/American Coonhound mix, who is absolutely terrified of water. Also, their two children, Alexandra and Ryan, can't walk him because he is pretty hyper and pulls badly on leash. Cesar has to resort to running with him to drain some of the energy. While Buddy was a little tired from the running, Cesar exposes him to a running hose, which he eventually accepts. Cesar recommends long daily walks and gradual exposure to water. After three weeks, Cesar returns to deal with Buddy's fear of baths. Ordinarily, Buddy trembles with fear while being bathed so Cesar uses food treats as a positive reinforcement to make the experience easier for Buddy. After the bath is done, Buddy flips out and tries to bite Cesar; Cesar explains that since Buddy couldn't express himself during the bathing process, he needed to vent. Cesar controlled Buddy without giving him attention until Buddy calmed down.

Humping Daisy

Daisy is a yellow Lab who lives with Marlene and Randy Benda and their two children. Daisy humps the kids, rushes the door and generally is hyper when the children's friends are visiting. Cesar notices that the Bendas encourage and empower their children, which is good, but they are doing the same thing with Daisy, which is not so good. They all go out into the back yard where Cesar works with Daisy. When they reenter the house, Cesar steps on her leash to hold her in place until she becomes calm and the family is able to enter the house first. Daisy's obedience training really helps the family to reach the next step in gaining psychological control.



Horsing Around

Rachelle Wyse has a three-year-old Golden Retriever/Sheltie mix named Sophie who chases and nips at the heels of the horses at the ranch where Rachelle keeps her horse, Jack. Cesar draws the connection of being in control of the horse without being mean, and relates that to how the relationship with a dog should be. He says that here in America we have humanized our dogs to an unhealthy degree, which is not fair to the dog. They take Jack into the arena to work out, and Cesar shows her how to stop Sophie from her escalating behavior of chasing and nipping at Jack. Cesar directs Sophie out of the arena and notes to Rachelle that he is not using Sophie's name while giving her directions; that her name is only used for a positive experience. He recommends a 45-minute power walk daily, and that she teach Sophie to respect Jack's space while he is exercising.
