Quite a few puppy owners do not realise that it's not just about training the puppy. it's also about training yourself.

You need to train yourself to take the puppy out as often as possible and most importantly, straight after a meal and as soon as it has woke up.

As said before, really praise the puppy when it pees/poops outside and simply ignore any accidents indoors. Don't rub it's nose into any accident and don't scold for any accidents indoors.

All dogs aim to please and love to be loved. It won't take long before it realises that doing what it should outside will get him lots of love

Good luck and be patient.
