how old is he?? the puppy.. not your husband
layla is 8 months.. STILL gets up once and a while at 3:30 am to pee... when you bring him outside.. is he peeing?? both times?? if this is the case.. you better tell your husband he is just a puppy.. and can't hold it... he can clean up the mess if he wants
Yorkies have such small bladders which is why they are usually a little harder to train... but you are lucky he is at least letting you know he needs to go out! if he is NOT peeing when you bring him out... and just waking you up.. then... well... i dunno.. i used to tell layla in a stern voice... no... and she would go back to bed... she just gave up... but if that won't work.. you might need to relocate him for a few nights until he gets the picture that you arne't getting up just because he wants to. good luck.. hopefully someone else will have other ideas too!
