Put your puppy in a crate or a safe area whenever you can’t supervise him. Always, always remember to take your puppy to his or her potty spot when they have to go! If they’re going in multiple areas, or a wide range, then A) you are more likely to stumble upon an unpleasant surprise while walking around your yard; and B) it’s easier for your puppy to create another potty spot by creating a habit of eliminating somewhere off-limits.
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.
