According to my observation, canine urine and especially from the female burns the grass. I used to have two large Bouviers de Flanders (originally of Dutch descent), and after seeing the damage they inflicted to the grass, I kept them away from my lawn. Actually, the male as one would expect, preferred the trees and fences rather then the lawn. Smaller dogs might not be so destructive, or maybe the grass killing strength / fertilizing effect depends also on the food they eat and type of grass.
On the other hand, human urine is actually quite beneficial to the lawn and it keeps it green. Before the feminists jump into the frey, it must be said that when it comes to watering the lawn, male urine is more effective and highly desirable. Allegedly, the scent keeps also the cougars and coyotes away from your front yard.

Our last two bitches were definitely untreated/unreconsctructed? bitches: the earlier one was about the size of a fox, the last one an alsabrador, which tells the tale (groan) of its own descent. They turned the lawn lushly dark and tough, even here in Spain, in the case of the big one. Being, apparently, creatures of habit, they both tended to favour the same location each time, and that concentrated devotion brough the colour into our lawn-lives. That there could well be a balance, a pH value that is critical, I know not. We never had male dogs and I wasn't, myself, much given to al fresco urinational urges - unless when we took the toboggan and kids to the local park, when the balance between pressure and possible frostbite kept me respectable.
Pee quality varies a lot, and I speak here not from a medical pov of which I know nothing, but from experience of life in a community where one of the rules is that no flushing, unless essential, take place between midnight and 8a.m. so as not to disturb light sleepers above or below one's own apartment.
What I discovered as I grew old, was that a couple of nocturnal visits to the can result in two possible morning greetings: benign lemonade or stingingly powerful beer, neither of which originate from the actual logical sources, as described, because I seldom touch them. Potent stuff, pee. Perhaps I should use a chamber pot for a while and empty it on the lawn to check the theories. However, that might result in a broken ankle, do perhaps not so clever for someone living alone, even if in the name of science.
We could perhaps start a new section on pee genres. Could prove of educational value.
