Just so you know, a puppy is never completely housetrained until they are 6 months old. For some breeds, even later. This means that though you may be making tremendous progress housetraining, there will be "mistakes". Sometimes for reasons you can't figure out! Don't fret about it. Stay focused on the progress you are making. Your confidence in the techniques you are using to house train your puppy will ensure your success.
When you're potty training a puppy, give the dog ample opportunities to relieve themselves outside and no opportunities to do so indoors. To do this, set a strict schedule of taking them out frequently. You'll also need to be aware of the most common times your puppy might have an accident, like when it's waking from a nap, a short time after it eats or drinks, or if it hasn't gone out for a couple of hours.
Crate training is a vital part of potty training success. As den animals, dogs can appreciate crates as a safe space, and as clean creatures, they’ll often want to keep that sleep space clean. A crate of the proper size is important, as one that is too large may convince the pup they have space to both sleep and eliminate. Puppy pads give dogs the option of relieving themselves in an approved spot indoors. However, these can be tricky to train with if you’re ultimate goal is to get the pup to only potty outside eventually.
Animal behaviorists assert that using dominance to modify a behavior can suppress the behavior without addressing the underlying cause of the problem. It can exacerbate the problem and increase the dog's fear, anxiety, and aggression. Dogs that are subjected to repeated threats may react with aggression not because they are trying to be dominant, but because they feel threatened and afraid.
In considering the natural behaviours of specific breeds of dogs, it is possible to train them to perform specialised, highly useful, tasks. For example, Labrador retrievers are the favoured breed for the detection of explosives. This is because of a combination of factors including their food drive which enables them to keep focused on a task despite noise and other distractions. Most working breeds of dogs are able to be trained to find people with their sense of smell (as opposed to their sense of sight). Cocker Spaniels are able to be trained as part of a termite detection team. Their relatively small size enables them to fit into small spaces, and their light weight allows them to walk on areas of ceiling which would be dangerous to anything heavier. In fact, although unusual, termite detection dogs are much more reliable at detecting termites than humans who rely on a basic system of tapping and listening. Because of their ability to learn signals by sight and for their energetic and athletic natures, German Shepherds are able to be trained for work alongside search and rescue teams and human apprehension teams.
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. 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. Pryor's dog training materials and seminars showed how operant procedures can be used to provide training based on positive reinforcement of good behavior. 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.
Lindsay says of this study, "Schilder and Van der Borg (2004) have published a report of disturbing findings regarding the short-term and long- term effects of shock used in the context of working dogs that is destined to become a source of significant controversy ... The absence of reduced drive or behavioral suppression with respect to critical activities associated with shock (e.g., bite work) makes one skeptical about the lasting adverse effects the authors claim to document. Although they offer no substantive evidence of trauma or harm to dogs, they provide loads of speculation, anecdotes, insinuations of gender and educational inadequacies, and derogatory comments regarding the motivation and competence of IPO trainers in its place." 
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. 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. It aims to "improve the health, happiness, and harmony of dogs and people – while helping both species learn from and support each other." Among other projects, the Foundation worked with Yale University to create a children's curriculum based on his work.
Confine your puppy to his, 'puppy-proofed' bathroom or an exercise pen and paper (or wee-wee pad) the entire floor. Put his bed, toys and food/water bowls there. At first there will be no rhyme or reason to where your pup eliminates. He will go every where and any where. He will also probably play with the papers, chew on them, and drag them around his little den. Most puppies do this and you just have to live with it. Don't get upset; just accept it as life with a young puppy. The important thing is that when you get home, clean up the mess and lay down fresh papers.
Strictly following the model set out in the Koehler Method of Dog Training, some 50 years later, the Koehler method continues to be taught in both class and private training formats. The method is based in the philosophy that a dog acts on its right to choose its actions. Koehler explained that a dog's learned behavior is an act of choice based on its own learning experience. When those choices are influenced by the expectation of reward, the behavior will most likely be repeated, and when those choices are influenced by the anticipation of punishment, they will most likely cease. Once the dog has learned that its choices result in comfort or discomfort it can be taught to make the correct decisions. Action→Memory→Desire encapsulates the learning pattern used by the method; the dog acts, remembers the consequences, and forms the desire to repeat or avoid those consequences. Adherents believe that once the behavior has been correctly taught, it should be performed, thus making any correction, fair, reasonable, and expected. While the model has been used consistently since 1962, some of the punishment procedures described in the book are now not considered necessary, humane, or appropriate by many trainers.
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.
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.
A dog learns from interactions it has with its environment. This can be through classical conditioning, where it forms an association between two stimuli; non-associative learning, where its behavior is modified through habituation or sensitisation; and operant conditioning, where it forms an association between an antecedent and its consequence.
