I Punish My Puppy How Should I Punish My Puppy For Pottying In The House?

How should I punish my puppy for pottying in the house? - i punish my puppy

I train my chest almost 4 months old Golden Retriever. He has never had an accident in his cage and waits for him outside to do his business. every morning and after every meal, when I went, he followed me to the door and goes to the bathroom. but if I play in the lounge for a moment, I am to pee and shit at random on the carpet. My friend had a dog and advised him to put his nose in the dining room so we can feel, and then beat his ass with a newspaper. Thus, the paper did not hit my hand. I thought it was a bit angry, but still, suggestions, without being physically?
