When you have to leave the puppy alone, you’ll need to confine it to a crate. This will prevent the puppy from peeing and pooping all over your home, and will also help teach it control, since it won’t want to soil the crate. However, young puppies need frequent bathroom breaks, so you’ll also need to ask a friend or pet-sitter to stop by and let the puppy out throughout the day until it’s old enough to go for longer stretches without needing to use the bathroom.
While your puppy is confined to the bathroom or his pen, he is developing a habit of eliminating on paper because no matter where he goes, it will be on paper. As time goes on, he will start to show a preferred place to do his business. When this place is well established and the rest of the papers remain clean all day, then gradually reduce the area that is papered. Start removing the paper that is furthest away from his chosen location. Eventually you will only need to leave a few sheets down in that place only. If he ever misses the paper, then you've reduced the area too soon. Go back to papering a larger area.
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.
Don't allow your puppy freedom outside of his room or pen unless you know absolutely for sure that his bladder and bowels are completely empty. When you do let him out, don't let him out of your sight. It is a good idea to have him on leash when he is exploring your home. He can't get into trouble if you are attached to the other end of the leash. Never, ever tie the puppy's leash to something and leave the puppy unattended.
Consistency and Patience. Never scold or punish your puppy for mistakes and accidents. The older your pup gets, the more he will be able to control his bladder and bowels. Eventually your pup will have enough control that he will be able to "hold it" for longer and longer periods of time. Let your puppy do this on his own time. When training is rushed, problems usually develop. Don't forget, most puppies are not completely house trained until they are 6 months old.
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".
It's an exciting time when you bring your new puppy home, but a new pet also comes with challenges. One of the first and biggest challenges that you may face is that of potty training. Some puppies will learn this quickly, while others will struggle with it for a while. During this training period, always remember to be patient, remain calm, and be consistent. If you stay positive and follow these guidelines, potty training can be a simple process.
Non-associative learning is a change in a response to a stimulus that does not involve associating the presented stimulus with another stimulus or event such as reward or punishment. Habituation is non-associative learning. An example is where a dog that reacts excitedly to a door bell is subjected to repeated ringing without accompanying visitors, and stops reacting to the meaningless stimuli. It becomes habituated to the noise. On the other side of habituation is sensitization. Some dogs' reactions to the stimuli become stronger instead of them habituating to the repeated stimuli or event. Desensitization is the process of pairing positive experiences with an object, person, or situation that causes fear or anxiety. Consistent exposure to the feared object in conjunction with rewards allows the animal to become less stressed, thereby becoming desensitized in the process. This type of training can be effective for dogs who are fearful of fireworks.
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." 
One of the easiest ways to prevent accidents is learning to recognize when your puppy needs to go out. Most puppies will sniff the ground when they’re getting ready to potty, but there are many other more signals that happen prior to sniffing. Puppies that pace, seem distracted and walk away from play are subtly signaling that they have to go out. If your puppy tries to sneak out of the room, take a potty break right away.
Whether you have a new pup, who is just starting out on his potty training journey, or you have an older dog that you’ve just adopted or rescued, I’m going to teach you about a process called shaping that will teach your dog to think for itself and solve problems on his own. If this is done consistently, I promise the rest of these dog training instructions will be a walk in the park!
Konrad Lorenz, an Austrian scientist who is regarded as developing the foundations of ethological research, further popularised animal behaviorism with his books, Man Meets Dog and King Solomon's Ring. 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).
