I would leave it alone. As you say, she was not in danger.

I wouldn't say anything but if I could catch the kid's eye I might say 'don't touch - that's yucky' or something

I probably wouldn't say anything, because like @MrBee I prefer not to intervene into other people's parenting unless it is a really major thing.

If it was someone I regularly saw at the park and had maybe made small talk with in the past, I might do like @Rubies and say "Oh no! I saw a dog pee on that before! Do you want a wet wipe for her?"

I probably wouldn't say anything. The dad should know better!

No I wouldn't say anything. As you said you were just assuming it was covered in dog pee. The dad could have/should have made the same assumption but didn't. It's gross but the kid's life wasn't in danger so I would leave it alone.

If it was something else that I know is covered in pee, then yes, I probably would mention something if I was close by. But like you mentioned, fire hydrants are notoriously covered in pee so I would assume the Dad already knows this and doesn't mind and not say anything.

I wouldn't say anything. Dried dog pee isn't dangerous. The fire hydrant might be less disease ridden than other stuff because peoples germy hands are less likely to touch it ;).
