Dog urine is made of a combination of ammonia, bacteria, hormones, and uric acid. As the urine breaks down, the ammonia concentration increases and sulfur-containing organic chemical substances known as mercaptans are then produced. If mercaptans are in the air, even at low concentrations, they are very noticeable — they are the same substances that give skunk odor and rotting cabbage a trademark stench!
For this reason, you should never clean up his pee pee with ammonia-based products. Similarly to how dogs love to mark and revisit old spots, the scent of ammonia can trick him into thinking it's an OK, previously peed upon place when potty time comes again. I'd even go so far as to not using this in a pet-filled home anyway as to not confuse a dog into using the freshly mopped kitchen floor as a prime bathroom break destination.
