The best way to potty train pup is to start from the moment you arrive home.
The best thing to do is to establish a routine and use a crate when you can't be with them.
Keep this experience positive and in no time your puppy will be asking you to go outside.
The use of a crate can help to speed up this process (dogs don't like to soil their sleeping quarters).
The most important thing is to set up a routine.
Schedule a bedtime, wake time, nap time and even what time your puppy eats its meals.
Dog's are creatures of habit and will adjust very quickly to this schedule.
Before/After these activities, take them out (young puppies have small bladders and need to go often).
If your puppy has an accident, don't scold them for their mistake.
Instead, just clean it up with a good cleaner and keep a closer eye on your puppy.
If you happen to catch them in the "act" instead of hitting (which can cause them to fear you and begin hiding when they need to potty), take outside and show them where to go.
When you potty train pup to go outside, make sure you go with them (so you can see that they go potty and not just play), take to the same spot every time.
Wait while puppy goes and praise them.
Let your puppy know you are proud of what they just did and in not time they will be asking you to let them outside.
