There are a variety of established methods of animals training, each with its adherents and critics. Some of the better known dog training procedures include the Koehler method, clicker training, motivational training, electronic training, model-rival training, dominance-based training, and relationship-based training. The common characteristics of successful methods are knowing the animal's attributes and personality, accurate timing of reinforcement and/or punishment and consistent communication. The use of punishment is controversial with both the humaneness and effectiveness questioned by many behaviourists.
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,[42] 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.[43] 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.[44]
This method is the most effective and flexible. Your pup needs to develop his natural "den instinct" and learn where to eliminate - and where not to. To potty train our puppy we must condition a desire in the pup to avoid soiling the "den" - your house. Confinement and your due diligence in providing access outside the "den" to potty and poop will develop this instinct and eventual desire. When and how to use confinement is described in detail below.

I know I keep mentioning this, but it is SO IMPORTANT for you to understand that in the dog potty training process, there are going to be accidents. What you do when your dog has an accident is very important. Yes I know that nobody likes cleaning up after the fact but if you react negatively your dog will start to associate your anger or frustration with him going to the bathroom and will be afraid to eliminate around you. I would say this is the biggest mistake people make while dog potty training.
A qualification can only be delivered by an awarding body which is regulated by a government body. The one you will most commonly see on site is OFQUAL, the government regulating body for England - but there is a different regulating body for each country in the United Kingdom, as well as the Republic of Ireland. Each regulating body maintains a list of the qualifications it regulates.
Dogs have become closely associated with humans through domestication and have also become sensitive to human communicative signals. Generally, they have a lot of exposure to human speech, especially during play, and are believed to have a good ability to recognize human speech. Two studies investigated the ability of a single dog that was believed to be exceptional in its understanding of language. Both studies revealed the potential for at least some dogs to develop an understanding of a large number of simple commands on the basis of just the sounds emitted by their owners. However the studies suggested that visual cues from the owner may be important for the understanding of more complex spoken commands.[81]
As your puppy becomes more reliable about using his toilet area and his bowel and bladder control develops, he can begin to spend more time outside his room or pen with you in the rest of your home. Begin by giving him access to one room at a time. Let him eat, sleep and play in this room but only when he can be supervised. When you cannot supervise him, put him back in his room or pen.

It's very important to put your puppy on a regular and timely feeding schedule; What goes in on a regular schedule will come out on a regular schedule. Every pup is different; some poop immediately after eating; with others it may be 30 minutes to an hour after eating. Unless advised by your vet for some medical reason, do not free-feed. That is, do not leave food out all the time. For two reasons: First, your pup's elimination schedule will be random at best. And second, she will not necessarily associate you as the provider of her food (see our article on being a pack leader and winning a puppy's respect and trust).

There also behavioral issues that can interfere with successful training. Urine marking is a normal dog behavior in which the animal will hike their leg and mark a certain area or object. With separation anxiety, the puppy may have accidents inside when you leave them at home alone. Some puppies become nervous or upset when their owners are away. Other puppies have a submissive or excitement urination problem. This causes them to spontaneously urinate during certain activities. Discuss these possibilities with your veterinarian or trainer if you're not getting positive results.[23]
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".
One of the biggest mistakes new puppy owners make is expecting their puppy to hold it for longer than he is physically capable. The general guideline for puppy “hold times” is that each month of age equates to an hour of “hold time,” so a two-month-old puppy can hold it for roughly two hours. There are exceptions to the rule; your puppy should be able to hold it for slightly longer period of time at night as he gets older and you pup will need potty breaks more frequently when he’s playing.
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]
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]
