How do I get rid of dog urine smell from concrete?

[peachhamster]

Just moved from a house with a large garden to one with a concrete yard and have three (large) dogs. They toilet in the yard, which is fine and I wash it down several times a day, but it's starting to smell. Have bought special kennel disinfectant, which works ... until one of them wees again just once and then it's full on stink. Can anyone pleeeeeease advise how I can keep the smell at bay? They do go out on long walks every day, several times a day, so it's not that they're cooped up. Thanks.

You gotta spray as much Brut 33 into that yard as you can and eventually the smell of dog piss won't seem so bad !

Domestos and a pressure hose.

Really, just bleach and the hose? I have a nozzle on it with different settings - like JET, which is used most of the time!!

Works for us

Give them their water just before they go out. My GSD learnt this trick himself, as soon as I pick up his lead he guzzled all the water he could. I expect your dogs will catch on too.

Jeyes fluid.

I used to use Jeyes Fluid when I had my dogs.

I was going to suggest Jeyes Fluid if you were worried about bleach

[wendilla]

Yes Tilly we typed that at the same time.

Thanks everyone. I know Jeyes will work, but I was worried about it putting them off going there. They have to be able to use it; I just want to obliterate the smell.
