Observational learning is the learning that occurs through observing the behavior of others. This form of learning does not need reinforcement to occur; instead, a model animal is required. While the model may not be intentionally trying to instill any particular behavior, many behaviors that are observed are remembered and imitated.[54] The domestic dog is a social species and its social dependency makes it aware of the behavior of others, which contributes to its own behavior and learning abilities. There is, however, ongoing discussion about how much, and how, dogs can learn by interacting with each other and with people.[55]
Dogs don’t speak English, and just because we might yell at our dog as we catch him in the middle of peeing on the floor and then rush him outside where he finishes it off… doesn’t mean we did an effective job at telling him that outside was where he was supposed to go. We are usually too focused on getting him NOT to go inside, instead of going outside.
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.
Typical positive reinforcement events will satisfy some physiological or psychological need, so it can be food, a game, or a demonstration of affection. Different dogs will find different things reinforcing. Negative reinforcement occurs when a dog discovers that a particular response ends the presentation of an aversive stimulus. An aversive is anything that the dog does not like, such as verbal admonishment, or a tightened choke chain.[41]

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:
