We're having a similar issue with Diego who is 8 weeks today. He has yet to poop in the house (we've got the right formula to prevent him from pooping, although we have caught him once in the house). With peeing, we haven't figured out the right formula just yet, but we're close.
Here is what we have so far for peeing:
1a) Crate training is helping a lot; he has yet to pee/poop in the crate and I think we're solid with him understanding that is his Den.
1b) Trigger word: make sure to associate a trigger word with the pee/poop and use the word often when you first bring him outside. During and after he does his business, praise with "Good whatever" and give him lots of praise when he runs to you after he's finished. We use the word "outside" and then "Good Outside".
2) Offer water before you take him out unless after 7pm at night
3) Take him out after long naps in the crate; run him a little if he doesn't pee right away
4) Take him out after each meal, which is necessary for a poop free house
5) The hard part: when he doesn't pee or poop after the above mentioned activities! This is where we're having a hard time 'detecting' his pre-pee symptoms! To counter this, we're starting to put him in the crate a little bit after outside time when he doesn't do his business. If he doesn't fall asleep, we'll wait a good 10 minutes, wait until he is calm and quiet, and then let him out and take him out again. We're also noticing exercise helps a lot here too (just a few laps around the pool, nothing strenous).
