My new Labrador puppy has just been busted for peeing on my old Persian Rug. Apparently she's been doing it for a week or so. I've shampooed it 3 times with a machine, and a disinfectant solution, hung it over the closeline for a couple of days, but I still cann't get the smell out of the rug. Any ideas how the smell can be dealt with, without getting rid of it. It's not a real Persian, but still nice.

I need to carpet both my bedrooms and have been researching price, installation, fibers, weights, etc. There are horrible reviews out there for every conceivable point of purchase! Kinda makes you want to do it yourself, but since I have extremely serious doubts about installing it myself, I'm now considering carpet tiles. How do these look once installed? Do they look like one piece or do they look like a checkerboard? I'd like to hear from anyone who has installed these and what they wished they'd done differently. Also, I'm putting them on a concrete floor. Any special prep required? Do the tiles have cushioning to them? Should I use a padding underneath - or is that even possible? Just like everyone else, the economy has me in a bind so price is an important issue, but I also want a good quality product! I'm open for suggestions!!
