I would take a potty pad outside with you when he goes out to potty and would immediately blot up the urine when he goes pee. Then I'd take that pad inside & put it down. He'll sniff it & recognize his pee. Then I'd take him to the pad at various times throughout the day and tell him to go potty.
All it takes is him just doing it one time & getting praised & treated to a yummy goody and he'll want to do it again.
Good luck!
