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: more on this
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.
Some people believe that the only way to transform a disobedient dog into a well-behaved one is to dominate her and show her who’s boss. However, the “alpha dog” concept in dog training is based more on myth than on animal science. More importantly, it leads misguided pet parents to use training techniques that aren’t safe, like the “alpha roll.” Dogs who are forcibly rolled onto their backs and held down can become frightened and confused, and they’re sometimes driven to bite in self defense.
If your dog isn’t giving you an obvious signal that they need to go out (like whining at the door) I suggest teaching them to ring a bell when they need to go outside. Some of the other signs dogs give that they need to go out such as pacing around or circling can be easy to miss if they’re in another room, which is why a noise based signal such as ringing a bell can make things easier.
To communicate clearly and consistently with your dog, you need to understand how she learns. Dogs learn through the immediate consequences of their behavior. The nature of those consequences determines how they’ll behave in the future. Dogs, like other animals (people included), work to get good things and avoid bad things in life. If a behavior results in something rewarding-like food, a good belly rub, playtime with dog buddies or a game of fetch with her pet parent-your dog will do that behavior more often. On the other hand, if a behavior results in an unpleasant consequence-like being ignored or losing things she finds rewarding-she’ll do that behavior less often. Are dog training classes worth it?
