Cesar Millan worked for the first time in a dog grooming shop after entering the US. He later set up the Pacific Point Canine Academy, one of his early customers being Pinkett Smith. After’ Los Angeles Times ‘ ran an article about him, Millan got domestic attention. He began working on the television pilot for’ Dog Whisperer’ with MPH Entertainment, Inc. in 2002. Millan began publishing ‘ Cesar’s Way ‘ magazine in the U.S. and Canada in 2009.

Dog training is the application of behavior analysis which uses the environmental events of antecedents and consequences to modify the dog behavior, either for it to assist in specific activities or undertake particular tasks, or for it to participate effectively in contemporary domestic life. While training dogs for specific roles dates back to Roman times at least, the training of dogs to be compatible household pets developed with suburbanization in the 1950s.
When you are home but can't attend to your puppy, follow the same procedures described above. However, the more time you spend with your puppy, the quicker he will be house trained. Your objective is to take your puppy to his toilet area every time he needs to eliminate. This should be about once every 30-45 minutes; just upon waking; just after eating or drinking; and just after a play session. Provide house training taxi service to avoid unnecessary "mistakes".
In May 2010, after his dog Daddy died in February and he learned of his wife's intent to divorce him, Millan attempted suicide.[42] In June 2010, Ilusión Millan filed for divorce.[43] In August 2010,[44] he began a relationship with Jahira Dar,[45][46][47] an actress and former stylist and wardrobe consultant.[48] They announced their engagement in April 2016.[48]
While working with a dog, Millan often uses vocal marks such as tsch,[33] gestures, and body language to communicate with dogs rather than speech or the dog's name. Millan encourages owners to create their own unique sound that works for them.[32] He believes that dogs sense, understand, and respond to a person's energy more easily than their speech.[34]
A satirized version of Millan was portrayed in "Tsst", the May 3, 2006, episode of the Comedy Central animated series South Park. In the episode, Liane Cartman enlists Millan's help in applying his principles to her misbehaving son, Eric Cartman. The principles work and Eric temporarily becomes completely reformed. However, in the end when he refuses to go on an outing with his mother, she caves in to his demands in order to persuade him to go along with her, thus reverting his behavior to its original state. In 2010, when Millan was asked if he was offended at all by the episode, he stated that the creators of the show (Trey Parker and Matt Stone) contacted him to inform him of their intentions beforehand and that he found the episode fantastic.[52] Millan reacted to the episode in a video posted on November 13, 2019 to his YouTube channel.[53]

Consistency and Patience. Never scold or punish your puppy for mistakes and accidents. The older your pup gets, the more he will be able to control his bladder and bowels. Eventually your pup will have enough control that he will be able to "hold it" for longer and longer periods of time. Let your puppy do this on his own time. When training is rushed, problems usually develop. Don't forget, most puppies are not completely house trained until they are 6 months old.
Clean up any accidents in your house completely with an enzyme cleaner. This is very important because you do not want your pup to smell somewhere he has previously marked because he will return to that spot again and again. And on that note… If Fido has an accident in front of you, and you scold, yell or punish, you will only teach Fido not to take his potty breaks in front of you – Do not punish for accidents.
Unfortunately, there is no magic length of time or milestone age when a puppy can be considered fully housetrained and there are many factors that go into how quickly a puppy can be potty trained. Your puppy’s age plays a major role during the initial phase of potty training, as a very young puppy won’t have the muscle control necessary to hold it for long periods of time.
If your puppy is not sleeping in her crate or pen, and is out in the house, you must follow her around to know what she is doing: chewing a bone, running circles, getting a drink of water, etc. In fact, don't take your eye off of her! If you cannot watch her continuously, you must put her back into her pen or crate to prevent potty training "mistakes".

Understand your puppy's particular breed behavior and needs. Research your dogs breed traits and special needs or any behavior that you should be aware of and look out for. For example, If your puppy is a tiny little chihuahua, their bladder will be very small and they will need to urinate more frequently; accidents will happen even if they are well trained.
Taxi your pup for about one month (until the pup is about 3 months old as this should give the pup enough time to develop some bladder and bowel control). By doing so, you will prevent many mistakes. At the same time you will train a stong preference in your pup to eliminate in your chosen spot. The pup will also learn that being picked up gets - kisses ! 

Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place."

Millan's work focuses on handling a dog with what he calls "calm-assertive energy".[9] He believes that dog owners should establish their role as calm-assertive pack leaders.[18] According to Millan, dogs have three primary needs:[18] exercise, discipline and affection, in that order.[30] In other words, it is the owner's responsibility to fulfill the dog's energy level needs through challenging exercise; then to provide clearly communicated rules, boundaries and limitations; and finally, to provide affection.[31] According to Millan, a common pitfall for American dog owners is to give a great deal of affection with very little exercise and even less discipline.[31] He encourages owners to understand the effect their own attitudes, internal emotions and physical postures have on a dog's behavior, counseling owners to hold strong posture (i.e., shoulders high and chest forward) and to project energy that is calm-assertive.[16][32]
Marian Breland Bailey played a major role in developing empirically validated and humane animal training methods and in promoting their widespread implementation.[14] Marian was a graduate student under B.F. Skinner. Her first husband Keller Breland also came to study with Skinner and they collaborated with him, training pigeons to guide bombs. The Brelands saw the commercial possibilities of operant training, founding Animal Behavior Enterprises (ABE). In 1955, they opened the "I.Q. Zoo" as both a training facility and a showcase of trained animals. They were among the first to use trained animals in television commercials, and the first to train dolphins and whales as entertainment, as well as for the navy.[14] Keller died in 1965, and in 1976 Marian married Bob Bailey, who had been director of marine mammal training for the navy. They pioneered the use of the clicker as a conditioned reinforcer for training animals at a distance.[13] ABE went on to train thousands of animals of more than 140 species.[14] Their work had significant public exposure through press coverage of ABE-trained animals, bringing the principles of behavior analysis and operant conditioning to a wide audience.[15]
