For the bush I would try one of the sprays you can get at the petstores. I have used one from PetCo that is green, looks like simple green, and it's done a good job. It's safe for pretty much everything, so I just spray it all over, on the grass, the kennel, the patio furniture, anywhere the dogs have gone. A friend gets one from PetSmart, once again, I don't know the brand, but it's also green and has a minty smell to it. She swears by it for her yard.

For the OP you might consider putting something in the kennel that can be removed once in awhile. I use pine or cedar shavings. They soak up the majority of the urine and I can just remove/replace them once in awhile. Because they aren't hard packed they also get more air/sun and dry better. And they will work down into the dirt, helping to loosen that up, which will also help with the odor. IMO they also make cleanup from poop easier, since I can scoop it up with a little bit of shavings, and have it all, vs the little bits left on concrete that you end up rinsing off into the ground around the kennel, unless you have a drain system.

I've used "SimpleGreen" on the ground with good luck, I've been using straw for ground cover for over a year now and have had no oder problems.

I used to use alot of barn dry before I put down concrete. It's like a wood stove pellet Works wonderfully and the dogs don't eat it. .

Thank you everyone. I now have options to try. I appreciate all the feedback.
I like the idea of the bleach solution. Do you think it would also be strong enough to work as a disinfectant? We have a stray dog problem and parvo is an issue where I live.
So far, I've been lucky, but I always worry.
Thanks again, everyone!

Honestly unless I had puppies in house I wouldn't make any extra effort to control parvo other than shooing dogs out of my yard or calling animal control.

I have no idea if the bleach solution will kill parvo. My guess is no.

Ok, just a thought. For the most part, the strays are avoiding me, I mean, my yard now. Actually, some of the neighbors are, too. LOL!
I wish we could lock up all dogs and neighbors.

If there is a Sherwin-Williams paint store near you you can purchase a product called Oxi-One its a a new "green" product that works well with heavy cleaning and also small cleaning scenarios, i use this on a daily basis in my kennels and on my jobs, it also works indoors on carpets to remove the pet odor, or urine smell if there is a mistake.

I know the feelin'. We had a near blood bath at the top of my driveway tonight. The neighbor's new dogo/american bulldog mix and the rottie who is left to wander the neighborhood at night got into it. Nights like this make me wish this county had a leash law.

I'm going to have to track down the rottie's owner again and see if I can convince him to at least tether up his dog for safety.

Wow, scary. So far most of ours are lovers, not fighters. I can guarantee at least two litters a year just off the neighbors odd little dog. Then there's the other pack of one female, three males....
It's a right proper Jerry Springer orgy for dogs out here. Yuck!

Interesting thing I have noticed though. We have had the dwarfism gene introduced out here and some breeds are really kind of cool looking with that thrown in. The dwarfed Shar pei is almost cool enough to try to catch. The wire haired stumpy legged things that run with it, OTOH *shudder* But, really interesting diversity if you just look at the phenotypes and try to imagine genotype. It's just, well odd and interesting, in a frustrating kind of way.

Hi Lisa, I have the same situation, and I have been thinking, of trying out charcoal. As recall that is what I used in my aquariums to eliminate ammonia. So why not in my small run, I would buy a bag and have fun smaching it in as much as I can.

I would be putting Down 12" pavers, after a clean up and mixing the charcoal with sand or dirt, then cover the pavers with stall mat hopefully for easy clean up. Dan
