Don’t punish your dog if they pee inside. Regardless of all those old training ideas punishment isn’t a good deterrent for house training. Yelling at your dog after the fact just confuses them and makes them nervous around you. If you catch your did in the act you can try to get their attention & move them outdoors. If you’re successful & they continue going once you get outside praise them like crazy.
Many owners appear disappointed that their young puppy will not toilet when out on a walk, yet relieves itself the second it gets back home. This is because the puppy has been taught to toilet only at home (hopefully in its garden), and being creatures of habit, they often wait until they have returned home before evacuating their bladder and/ or bowels.
Suppose you consistently praise your puppy for their actions, while potty training. Then say your dog has an accident. Do not praise you dog immediately. Instead, take your dog outside and wait for it to go to the bathroom. When it finishes doing its business, take it inside, and keep it in a separate room while you clean up the mess. After this you should act disappointed in your dog, but only for a few minutes. Keep you and your dog motivated to potty train.
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.
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:
Remember that training is an ongoing process. You will never be completely finished. It is important to keep working on obedience training throughout the life of your dog. People who learn a language at a young age but stop speaking that language may forget much of it as they grow older. The same goes for your dog: use it or lose it. Running through even the most basic tricks and commands will help them stay fresh in your dog's mind. Plus, it's a great way to spend time with your dog.
