i have a very small, 4lb dog that has bladder issues and sometimes can't hold it until I get home for lunch. I usually have the door shut to keep them from getting in the rooms with carpet and one with a rug (only two rooms) but my son didn't shut his gate and someone left the other door open. I have tried vinegar and water (which is what I usually use) but for some reason it's not working! What else will work on carpet and get out the smell that's safe? I know most people love F10 but will it get smells out?!?
