It’s best not to punish the puppy for making a mistake. Instead, focus on praising appropriate bathroom behavior. If you catch your puppy in the act, interrupt it by saying “No!” in a firm voice or clapping your hands loudly, then take the puppy outside to finish going to the bathroom. Never swat your puppy, yell at it, or try to rub its nose in the mess.
Clicker training, a common form of positive reinforcement, is a simple and effective dog training method.

With clicker training, you can easily and effectively teach your dog all kinds of basic and advanced commands and tricks. It's fast and easy to learn how to clicker train your dog
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.
The process is the exactly same for older dogs as it is for puppies; prevent accidents from happening by using baby gates and a crate if possible, create a predictable schedule, learn to recognize your dog’s potty signals, accompany your dog outside and immediately reward for all outdoor elimination, properly clean any accidents and supervise your dog until you’re sure that he understands the rules.
