Do not pour bleach on an item your dog has peed on. There is enough ammonia in dog pee (and maybe cat pee too, dunno) to cause the bleach to release chlorine gas. Which at the least is painful to the eyes and lungs, and at most can kill you.
This is what I learned yesterday.
Let’s be careful out there folks!
… an episode of “CSI: Kentucky” in here someplace.
Vary the amounts of chlorine or ammonia, and you get other hazardous reactions.
As long as we’re on the subject, don’t mix bleach with any of those lime/rust removers, like CLR. Wooooooofah. Bad stuff.
So no one is going to ask me how I came upon this tidbit of info?
Interesting web site, Skelji.
Is it a carpet? Don’t even bother trying to get the dog pee out. That’s pretty much impossible.
Just have him pee on the rest of the carpet to get a nice uniform color and pretend that’s what it’s supposed to look like.
Much easier. 
Actually our carpet is almost white, and using a dab of bleach on a sponge will nicely get out most stains. Never had any problems with that.
The learning experience I had yesterday actually came from an incontinence pad I’d put on the carpet to protect it from further incidents. Our female is having some ‘issues’ and at least we’ve got her at the point where she goes on the pad if she’s having a problem.
Anyway, the pad is large, soft, very absorbent and washable. I put it on top of the washing machine and poured some bleach on the spot, intending to rub it in to the spot and pop it in the wash. Well, imagine my surprise when it started to boil. Then I was hit with a wave of gas that darn near knocked me on my butt. Never occurred to me that dog piss and bleach would react with each other.
And in a related story . . .
The cleaning crew here at work likes to “freshen up” the urinals. They sometimes pour bleach in them (I guess the little cakes aren’t enough).
Not too long ago, it seems I was the first to pee that morning (the light was still off in the bathroom).
At the time, I was still a little tired (not a morning person).
I woke RIGHT THE HELL UP mid-stream:
“Arrggghhhh! My eyes! Chemical attack!”
Forget coffee. Nothing like a little piss 'n bleach to get your motor going.
I thought it was a misunderstanding about bleach and ammonia - it isn’t chlorine gas that’s produced when you mix bleach and ammonia. That would kill you dead. It’s, I think, chlorides? Which are irritating and bad to breathe but not a chemical weapon. Do I understand incorrectly? I’m not sure where I read that, and I can’t find it with a quick google, but I’d like to know for sure.
Oh, and I didn’t think about the fact that soap-scum-descummer would have ammonia in it when I used a bleach cleaner in the shower last week, and suddenly there seemed very much to be not nearly enough air in the windowless bathroom. Ack!
Accidently setting off one of those portable fire extinguishers in a van with all the windows uo will cause the air to be sucked out of the van and make the inhabitants do Blow-Fish faces on the window as they gasp for breath as the window slides downward.
Witnessed it first hand.
Kinda funny too.
All I have to say is, that is really, really cool.
Oh, sorry about whatever your dog pissed on.
