Does anyone know how to stop puppy biting? And puppy potty training?

I was given a puppy he just turn 13 weeks but damn he got sharp ass teeth to the point he left small holes in my leg after biting nipping me. Does anyone have any tips?


And the puppy potty training. When I take him out I would even take him out for hours and when we come back in few min later he does his business. Does anyone know. How to quit that shit and to tell me when he needs to go out?


Any other ideas u have?
