Thank you guys for your help . Yes , looks like I am getting closer to some type of solution . I have found some home made recipes with vinegar , 3 % hydrogen peroxide and baking soda . I have made a gallon of this natural home remedy and used it outside . Yes , the problem is only outside , fortunately they are good and clean inside the house , so no need for cleanup .
Thank you again

I've heard that vinegar is good for getting rid of smells too. If you use white vinegar it doesn't smell so bad as the brown vinegar.
Ordinary water might help too. If you hose down the yard? Or if that would make it muddy, maybe put water on the pee-spots.
I've heard that female dogs like to find the scent of where they did a pee last, to do it again in the same place, whereas male dogs are more likely to do it in many different places all around.
You know I cant swear to this but my Momma used to wipe any' mess' with vinegar she said it neutralised the smell, only thing is you may end up with a house that smells like an English 'Chippy" .... ....
