Well, I hate to differ with him, but if you do a search on the internet, vinegar(white) mixed with some water works wonders..it stinks to us, but it doesn't smell like the dogs pee...Believe me, My mother who is 81, has used it since she had dogs, and she's had them all her life...and as far as the smell, I've used it before, my dogs smell it and run away from it, they sure don't pee there the 2nd time |
