Konrad Most began training dogs for police work in Germany, and was appointed principal of the State Breeding and Training Establishment for police dogs in Berlin, where he carried out original research into training dogs for a broad range of service tasks. At the outbreak of war in 1914 he was charged with organising and directing the use of dogs to further the war effort. He headed the Experimental Institute for Armed Forces' Dogs during the Second World War, and afterwards ran the German Dog Farm, a centre for the training of working dogs, including assistance dogs for the blind. He played a leading role in the formation of the German Canine Research Society and Society for Animal Psychology.[10] His 1910 publication, Training Dogs: A Manual, emphasised using instinctive behavior such as the prey drive to train desired behaviors, advocated the use of compulsion and inducements, differentiated between primary and secondary reinforcers, and described shaping behaviors, chaining components of an activity, and the importance of timing rewards and punishments. The book demonstrated an understanding of the principles of operant conditioning almost thirty years before they were formally outlined by B.F. Skinner in The Behavior of Organisms.[11] While publishers of the 2001 reprint warn that some of the "compulsive inducements" such as the switch, the spiked collar and the forced compliance are unnecessarily harsh for today's pet dogs,[12] the basic principles of Most's methods are still used in police and military settings.[13]
While indoor elimination solutions like potty pads and litter boxes have their place, using them can actually slow the process down if you plan to eventually have your dog eliminate exclusively outside. Teaching your puppy to potty inside sometimes and outside others can be confusing because you will eventually have to teach your dog that at some point the indoor option is no longer allowed. Potty pads work best for people who can’t get their puppy outside quickly, like those who live in high-rise apartments or have limited mobility.

With Ilusión Millan, his former wife, he founded the Millan Foundation – later renamed the Cesar Millan Foundation and currently called the Cesar Millan PACK Project.[13] The foundation was established to provide financial support to animal shelters and organizations engaged in the rescuing, rehabilitating, and re-homing of abused and abandoned animals, and to fund spay/neuter programs to help reduce dog overpopulation.[14] It aims to "improve the health, happiness, and harmony of dogs and people – while helping both species learn from and support each other."[15] Among other projects, the Foundation worked with Yale University to create a children's curriculum based on his work.[9]

Konrad Lorenz, an Austrian scientist who is regarded as developing the foundations of ethological research,[16] further popularised animal behaviorism with his books, Man Meets Dog and King Solomon's Ring.[17] Lorenz stated that there were three essential commands to teach a dog: "lie down" (stay where you are), "basket" (go over there) and "heel" (come with me).[18]
Though it differs by each individual dog this is the time when most will come up with their own little way of letting you know they’ve got to go. It might be crying at your feet, ringing a bell you’ve set up or waiting at the door — just be sure to pay attention to these signals & follow up. Once your dog knows how to get your attention when he’s got to go you can relax a little and congratulate yourself on a job well done.
It’s best not to punish the puppy for making a mistake. Instead, focus on praising appropriate bathroom behavior. If you catch your puppy in the act, interrupt it by saying “No!” in a firm voice or clapping your hands loudly, then take the puppy outside to finish going to the bathroom. Never swat your puppy, yell at it, or try to rub its nose in the mess.
Prior to the 1980s, Karen Pryor was a marine-mammal trainer who used Skinner's operant principles to teach dolphins and develop marine-mammal shows. In 1984, she published her book, Don't Shoot the Dog: The New Art of Teaching and Training, an explanation of operant-conditioning procedures written for the general public.[25] In the book Pryor explains why punishment as a way to get people to change often fails, and describes specific positive methods for changing the behaviour of husbands, children and pets.[35] Pryor's dog training materials and seminars showed how operant procedures can be used to provide training based on positive reinforcement of good behavior.[25] Pryor and Gary Wilkes introduced clicker training to dog trainers with a series of seminars in 1992 and 1993. Wilkes used aversives as well as rewards, and the philosophical differences soon ended the partnership.[36]
In 1935, the American Kennel Club began obedience trials, and in the following years popular magazines raised public awareness of the benefits of having a trained pet dog, and of the recreational possibilities of dog training as a hobby.[19] After WWII, the increasing complexities of suburban living demanded that for a pet dog's own protection and its owner's convenience, the dog should be obedient. William Koehler had served as principal trainer at the War Dog Training Center, in California, and after the war became chief trainer for the Orange Empire Dog Club—at the time, the largest dog club in the United States—instructor for a number of breed clubs, and a dog trainer for the Walt Disney Studios.[20] In 1962 Koehler published The Koehler Method of Dog Training, in which he is highly critical of what he calls "tid-bit training techniques" based in "the prattle of 'dog psychologists'".[19] Amongst the training innovations attributed to Koehler is the use of a long line in conjunction with a complete absence of oral communication as a way of instilling attentiveness prior to any leash training. Koehler insisted that participants in his training classes used "emphatic corrections", including leash jerks and throw chains, explaining that tentative, nagging corrections were cruel in that they caused emotional disturbance to the dog.[21] Vicki Hearne, a disciple of Koehler's, commented on the widespread criticism of his corrections, with the explanation that it was the emotionally loaded language used in the book that led to a number of court cases, and to the book being banned in Arizona for a time.[22] Despite the controversy, his basic method forms the core of many contemporary training systems.[23]

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.
The next step is to teach your dog to ring the bell for a treat. Your dog has to be motivated to ring the bell, and in the beginning going outside isn’t enough to motivate him. But, if you teach him to ring the bell for a treat, he will quickly learn to ring the bell. You’ll want your dog to ring the bell with his nose, so make sure you hang the bell so it is nose level.
Teach your dog where he SHOULD take his potty breaks, instead of trying to use punishment to teach him where he should NOT go potty. If you focus on what you want him to do, instead of what you don’t want your dog to do, you’ll get faster results. Teaching your dog where it’s OK to go is very important, and one of the reasons why so many people are never successful in potty training their dogs.

A training class is not there to train your dog. Its purpose is to teach you to train your dog so you will need to be committed to train your dog for short sessions (5 minutes) several times a day rather than just simply turn up for classes! This little bit of training everyday will be repaid with a lifetime of living with a well behaved dog. You will also learn to avoid problems before they begin as well as receive help to overcome any that you already have with your dog.
