When puppies have to pee:

- Right after waking up from any nap they take
- Right before they go to sleep at night
- approx. 10 minutes after each play session
- approx. 15 minutes after each drink of water they take, no matter how big

Just a tip lol.. learn from my mistake:
Waking him up and taking him out at 3:00 AM will get him into the habit of doing that when he's older so you're woken up at 3:00 AM every night, for the rest of his life. LOL
