So, depending on how old he is and the size of your puppy, it’s unrealistic to expect him to be potty trained before this time. It will be helpful to keep in mind that your puppy is only able to hold their bladder 1 hour for every month old he is. So if your puppy is two months old, they can hold it for about two hours. Don’t go longer than this between bathroom breaks or they’re guaranteed to have an accident.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
There is nothing inherently wrong with telling your dog “no,” except that it doesn’t give him enough information. Instead of telling your dog “no,” tell him what you want him to do. Dogs don’t generalize well, so if your dog jumps up on someone to say hello and you say no, he may jump higher or he may jump to the left side instead of the right. A better alternative would be to ask him to “sit.” Tell him what you want him to do in order to avoid confusion.
The term "observational learning" encompasses several closely related concepts: allelomimetic behavior or mimicking where, for example, puppies follow or copy others of their kind; social facilitation where the presence of another dog causes an increase in the intensity of a behavior; and local enhancement which includes pieces of social facilitation, mimicking, and trial-and-error learning, but is different from true observational learning in that the dog actively participates in the behavior in the presence of the other dog and/or other environmental cues.[55] Four necessary conditions for observational learning are: attention, retention, motivation, and production. That is, the dog must pay attention to the dog or person performing the modelled behavior; retain the information gathered about the behavior during the observation; be motivated to reproduce the behavior in a time and place removed from the original; and finally, produce the behavior, or some reasonable facsimile thereof.[55]

Classical conditioning (or Pavlovian conditioning) is a form of learning in which one stimulus, the conditioned stimulus, comes to signal the occurrence of a second stimulus, the unconditioned stimulus.[45] Classical conditioning is when a dog learns to associate things in its environment, or discovers some things just go together. A dog may become afraid of rain through an association with thunder and lightning, or it may respond to the owner putting on a particular pair of shoes by fetching its leash.[46] Classical conditioning is used in dog training to help a dog make specific associations with a particular stimulus, particularly in overcoming fear of people and situations.[47]

Millan's first job in the United States was at a dog grooming store. He later created the Pacific Point Canine Academy. Jada Pinkett Smith became one of Millan's first clients and supporters when he was working as a limousine driver,[6] providing him with an English tutor for a year.[17][18] Subsequently, Millan created the Dog Psychology Center, a two-acre (0.81 ha) facility in South Los Angeles, specializing in working with large breed dogs.[23]
A dog learns from interactions it has with its environment.[1] 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.[2]
Millan's work focuses on handling a dog with what he calls "calm-assertive energy".[9] He believes that dog owners should establish their role as calm-assertive pack leaders.[18] According to Millan, dogs have three primary needs:[18] exercise, discipline and affection, in that order.[30] 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.[31] 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.[31] 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.[16][32]
Once he seemingly has this idea down, move the string of bells to the left or the right of your dog and see if he moves to go and hit them with his nose; if he does click and treat! Next try moving the bells above his head and then closer to the floor. If he is chasing them with his nose in an attempt to ring them, then he understands what you want!

There is only one acceptable methodology for potty training a dog of any age: positive reinforcement. Traditional advice suggested swatting a dog or rubbing his face in his waste for mistakes in the house, but those techniques do nothing to make the potty training process more understandable for your dog and can actually damage your relationship with him. Keep in mind, dogs don’t view their waste the way we do – to them, pee and poo is pretty interesting! Punishing your dog for going in the house won’t help him understand what he should do instead and might make him afraid to go near you at all, inside or out. Successful potty training requires patience, kindness and remembering that your new puppy is just learning the rules.
