I bought a used rug recently that smells. The seller eventually told us that there had been a dog around that may have done his business on it. The rug is clean and I have since tried those sprays that are meant to neutralize old urine smells. The smell still won't go away. It *MAY* have diminished slightly but I'm not sure. Should I continue with doses of these sprays or is it a lost cause?
If it's truly an old urine smell the dog must have pissed all over it every day for months.
Thanks.
