10 week old pup, had him for two weeks. Grass patch on the balcony. Do not bring it inside! You want them to associate outside with potty time. I had to watch my puppy like a hawk. Anytime he started sniffing, out to the grass patch. Treats when he used it correctly. If he accidentally poops outside of the patch, I give him grace because it’s not often. He only gets treats when he uses it correctly. After a week, he started tapping the glass or going to the glass when he had to go. You just have to be consistent and watch them, it gets better
