I've never bothered to train mine to "let me know". I just take them out at intervals appropriate for their age, and by the time they're 6 months or so they can hold it all day and all night. My current pup is 13 weeks and I let him out every 30-45 minutes while he's awake. At night he can hold it 5-6 hours so far.
