We recently had a well drilled. My other half joked to the driller about how he would have to keep our dog from peeing on it because it stuck up out of the ground like a fire hydrant. The driller said not to let our dog pee on it that the urine could eat through the steel casing. I found this very hard to believe considering it is steel. I don’t doubt that dog urine could eat through a lot of things, but steel casing?
Yep. Urine is extremely corrosive.

MSDS sheet for urea, a component of urine.

Bottom line (heh): Cover it with something plastic, or fence it off, so the dog doesn’t pee on it.
My office has brushed steel dividers between the urinals. They’re just 18" wide by 36" tall, made of sheet metal, riveted into hollow panels that are mounted to the wall to provide some privacy from the pisser next to you.
When I started here they were already corroded. Apparently, the janitors never clean them. From waist level down, piss splatter from the urinals had pitted and corroded them to the point where they were pretty much a solid sheet of rust.
Over 14 years later, they still haven’t been cleaned. And the rust has eaten holes in them.
Umm… my office building… office building.
For the record, I do not have urinals in my office.
However, the smell of whatever my coworker just cooked in the microwave sure makes it smell like I do. 
There are several manufacturers of “Waterless or Flushless Urinals.”
Men only for now, maybe “Unisex” models later.

Pays for itself in water savings.
‘They’ claim they are being installed in large public arenas to minimize odors, and health concerns as well as save water costs.
Usually urine is sterile but chemically a bad actor none the less.
Thanks DDG for information. I guess the real question would be is there anything that dog urine can’t destroy?
I will take your suggestion and fence that area off. Someone said they make fake looking rocks that you can place over them but I think this one sets to high out of the ground for that. It would have to be a boulder in this case.
watch out form Chinese stainless steel. My bbq rusted in less than 1 year and it was undercover!

You may not have noticed but this thread is 9 years old. Some of the folks that posted may not even be here anymore. Just an FYI.
Some of the best posters we’ve had have just stumbled across us though. I hope you’ll stick around, I think you’ll like it here.
imagine what zombie piss will do to steel
