In 2009, Millan launched Cesar's Way magazine in the United States and Canada, for which he was the Editorial Director. The magazine combined advice from Millan along with articles about the relationship between dogs and humans. Cesar Millan's Leader of the Pack was an American documentary television series on the Nat Geo Wild channel which ran from January 5, 2013 to March 26, 2013. The next year, 2014, saw the premiere of Millan's new series, Cesar 911, on the Nat Geo WILD channel; in non-American markets, it's known as Cesar to the Rescue. In 2015, he teamed up with children's television veterans Sid and Marty Krofft to create Mutt & Stuff, a preschool television show for the Nickelodeon channel. Millan's son Calvin stars on the series. In 2017, Millan and his older son Andre appeared in a new series Cesar Millan's Dog Nation, which ran for one season starting on Friday evening, March 3.
Punishment is operationally defined as an event that lowers the probability of the behavior that it follows. It is not "punishment" in the common sense of the word, and does not mean physical or psychological harm and most certainly does not mean abuse. Punishment simply involves the presentation of an undesired consequence (positive punishment) when the wrong behavior is performed, such as a snap of the leash, or the removal of a desired consequence (negative punishment) when the wrong behavior is performed, such as the trainer eating the cheese that would have been the reward. A behavior that has previously been developed may cease if reinforcement stops; this is called extinction. A dog that paws its owner for attention will eventually stop if it no longer receives attention.
The term "observational learning" encompasses several closely related concepts: allelomimetic behavior or mimicking where, for example, puppies follow or copy others of their kind; social facilitation where the presence of another dog causes an increase in the intensity of a behavior; and local enhancement which includes pieces of social facilitation, mimicking, and trial-and-error learning, but is different from true observational learning in that the dog actively participates in the behavior in the presence of the other dog and/or other environmental cues. Four necessary conditions for observational learning are: attention, retention, motivation, and production. That is, the dog must pay attention to the dog or person performing the modelled behavior; retain the information gathered about the behavior during the observation; be motivated to reproduce the behavior in a time and place removed from the original; and finally, produce the behavior, or some reasonable facsimile thereof.
