How can I train my 2 months shih tzu to do in the right spot not on the carpet, I used newspapars, dog pads but non was good :)

Read through the sticky at https://www.askmehelpdesk.com/dogs/housebreaking-42521.html

I advise against indoor pads or papers, but the methods in the sticky should still work. It should have some other help for you. Look at the other stickies at the top of the ''Dogs'' forum.
