My partner has cautioned me that if we don't take our 6 month old puppy outside to pee within 30 minutes after mealtime, he's at risk for developing a urinary tract infection!

I've searched all combinations of "uti" "housetraining" "puppy" and "post mealtime", etc., and I can't seem to find anything that even gestures to this risk. Can you help point me in a direction that explains this?

(As far as I can tell a bacteria of some kind must be present for a urinary tract infection to take place.)
