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.
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.
I don't teach or recommend so-called "purely positive" methods that allow misbehaving pups to continue misbehaving, instead of teaching them which behaviors are and are not allowed. "Purely positive" is fine for teaching tricks and high-level competition exercises, but NOT for teaching the solid good behaviors that all family dogs need to know, and NOT for stopping behavior problems such as barking, jumping, chewing, nipping, chasing, etc.
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.
Consistency is crucial. This may mean taking time off work to be there to take the pup outside every 20-30 minutes when they are awake. Crate training will also help the 'penny drop' as it teaches the pup to hold on until taken outside. Then, be sure to stay with the pup in the yard so you are there to reinforce how clever they are when they do go in the right place.
Success is usually attained in small steps. Training sessions with your dog should last 10 to 15 minutes, two to three times per day. This is especially true for puppies because of their very short attention spans. Longer sessions can cause an adult dog to become bored. Start by teaching basic commands. Try to stick with one action per training session so your dog does not get confused.
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.
