I believe (but I could be wrong) that bleach has amonia in it and you don't want to clean a pee spot with anything amonia because it has a urine smell to it and will only attract a dog to go in that spot again.
What you want to do is neutralize the pee smell with a neutralizer (not a deoderizer). You will need to use something like Simple Solution or Nature's Miracle. You should clean the mattress with it (I would saturate the area) and then I might even clean the bed clothes with some in the wash (along with your detergent). |
