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. 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. 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'". 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. 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. Despite the controversy, his basic method forms the core of many contemporary training systems.
The principle behind using a crate for housetraining is that dogs are very clean creatures and don’t like a urine-soaked rug in their living spaces any more than you do. It’s important that the crate is the right size—just large enough for the dog to lie down, stand up, and turn around. If it is too large, the dog will feel that it’s OK to use one corner for elimination and then happily settle down away from the mess. Many crates come with partitions so you can adjust the size as your puppy grows.
Millan's work focuses on handling a dog with what he calls "calm-assertive energy". He believes that dog owners should establish their role as calm-assertive pack leaders. According to Millan, dogs have three primary needs: exercise, discipline and affection, in that order. 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. 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. 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.
Electronic training involves the use of an electric shock as an aversive. Common forms are collars which can be triggered remotely, or that are triggered by barking, fencing that delivers a shock when a dog wearing a special collar crosses a buried wire, and mats that can be placed on furniture to deliver a shock. Some aids deliver an aversive such as a spray of citronella when triggered. The use of electric shock aversives for training dogs is the subject of considerable controversy. Supporters claim that the use of electronic devices allows training at a distance and the potential to eliminate self-rewarding behaviour, and point out that properly used, they have less risk of stress and injury than mechanical devices, such as choke chains. Opponents cite the risks of physical and psychological trauma associated with incorrect or abusive use.
Every dog needs to learn to walk on a leash. Besides the fact that most areas have leash laws, there will be times when keeping your dog on a leash is for his own safety. Learn how to introduce your dog or puppy to the leash, then teach him how to walk properly on the leash, even beside you on a bike. A loose leash walk teaches your dog not to pull or lunge when on the leash, making the experience more enjoyable for both you and your dog.
