I would take the plunge and pull up the carpet now and replace it rather than live with a smell on a suspect carpet and pad until I had time to get around to it--that day is a long way off and meanwhile who knows what is in the carpet?
Rainy day, supposed to be a rainy week, making it more difficult to get out for exercise or mowing. I'll have to see what I can work in. Still sticking with the diet. Doggedly.
