Puppies / Dogs don't urinate to convey displeasure or spite or for attention. They just aren't wired that way. As humans, WE'D do it....but not dogs.
If you are 100% sure that it's not a medical condition (and I'm not sure it isn't, they don't squeeze out a little bit for spite) then I'd have to take a deep look into what it is YOU are doing to set the pup up to succeed. If there is a lot of emotions running around your home, that could cause adverse conditioning on your pup too.
The idea is to figure out what the trigger is and to disregard any thoughts you might have that the pup is doing it on purpose for attention.
