How do I get rid of the smell of dog pee in my yard and patio?

For the lawn you try putting lime down to neutralize the soil. For the patio Make a spray solution with baking soda and white vinegar and leave on long enough to hopefully absorb the odor.

Mean Green makes a yard odor neutralizer, or basic lemon dish soap and vinegar mixed in water, you can also try just baking soda.

Baking soda should do the trick.

maybe white vinegar in warm water , guess a good slug in bucket warm water and slosh around , or maybe put in spray bottle and spray on worst areas .

I wonder if you have the plants that are around our local hospital. ANY time you go in the front doors it smells like pee! I finally found out it is a type of evergreen that is growing around their doors. It is not nearly so bad now that I know it is not from dog or cat elimination....LOL

Bleach then hose. Hydrogen peroxide works well too.

I use odo ban

its like carpeting...it soaked in. try a vinegar soak

treat your yard with lime
