Just as a child needs a caring parent; an athletic team needs a coach; your puppy needs a leader and a clear social hierarchy. If you do not take up the role of leader, your dog will; and you will end up with an unruly, disobedient dog. Many people try to win their new puppy's love by letting the puppy always have its way. Buckets of affection is a wonderful thing for most puppies, but it must be tempered with respect.
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.

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 great way to start your puppy off on the right paw. Dogs have a natural instinct to keep their den clean, so a properly sized crate, introduced gradually, will create a home base for your puppy and will keep him from having accidents when you can’t watch him. Use the crate when you’re unable to give your puppy your full attention during the day, as well as at nap time and bedtime. Selecting the right size crate is critical, and it should be big enough so that your puppy can comfortably stand up, turn around and lie down but not much bigger. If you opt for a crate that’s too large, your puppy will be able to potty in one corner and sleep comfortably in the other, defeating the purpose of crate training.
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.

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.
One of the biggest mistakes new puppy owners make is expecting their puppy to hold it for longer than he is physically capable. The general guideline for puppy “hold times” is that each month of age equates to an hour of “hold time,” so a two-month-old puppy can hold it for roughly two hours. There are exceptions to the rule; your puppy should be able to hold it for slightly longer period of time at night as he gets older and you pup will need potty breaks more frequently when he’s playing.
Every time your dog pees or poops outside it needs to be celebrated. Give them baby talk or a treat, jump up & down, pat their little heads & remind them of how brilliant that decision was. Yes it might look silly, but your pup needs to know he’s done the best thing ever. When you consistently praise your puppy for going potty outside they’ll start to understand that it’s the correct decision, and one that leads to super fun happy time.
Though it differs by each individual dog this is the time when most will come up with their own little way of letting you know they’ve got to go. It might be crying at your feet, ringing a bell you’ve set up or waiting at the door — just be sure to pay attention to these signals & follow up. Once your dog knows how to get your attention when he’s got to go you can relax a little and congratulate yourself on a job well done.
When you have to leave the puppy alone, you’ll need to confine it to a crate. This will prevent the puppy from peeing and pooping all over your home, and will also help teach it control, since it won’t want to soil the crate. However, young puppies need frequent bathroom breaks, so you’ll also need to ask a friend or pet-sitter to stop by and let the puppy out throughout the day until it’s old enough to go for longer stretches without needing to use the bathroom.
Positive reinforcement is the key to success. A common mistake is to punish your dog during training or become angry. This will only cause confusion. You can try to hold your dog's attention with treats and enthusiasm, but know that it is time to end a session when your dog becomes bored or tired. Try to end sessions on a positive note. Eventually, successful training will be achieved with patience and consistency.
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.
