No idea about the UTI. I could always message the friend and ask.
When we first got our boy, he understood this all too well... and then proceeded to figure out how he could **** his leg and pee through the bars to outside the crate, thus *technically* not breaking the rules..... He's a smart little ******* at times!!!If it pees in a smallish crate it probably has a water infection, most dogs won't soil a confined space unless they can't help it.
Hearts melter.
Does the crate have a divider? The space she should have in the crate should be just enough for her to stand up and turn around.
Both my dogs were toilet trained by 5months. Both have had the very occasional accident when unwell since, but generally can be relied upon to not go in the house.
I'm not sure what you want from this thread, unless its just to vent. I mean, you're right we could give you tips on toilet training (which you don't need anyway), but there's no point as the pup will only be with you a short while. I think all you can do is get her outside as often as possible and accept that its going to be a slightly stressful few days/weeks then remember the experience when you're asked to help out in future. You perhaps want to say no next time.
She is cute though.

Not sure if it is her first dog or not. I know her mum has had a few dogs, I guess shes just getting tips from her.Poorly trained and Rottweilers seem to go hand in hand, still a puppy though so there's still hope yet. Out of interest OP is this your friend's first dog?
