Pets and odors

So thanks to what I'm dubbing as my "all the time sickness" I'm already having a hard time functioning because I can't eat really, or be around smells, so I can't do my dishes and I can hardly stand going out. It's been very hard at work to be next to people who I probably wouldn't have noticed before but now to me reek of the most god awful smells. One thing that has been bothering me the most is the fact that I now smell dog urine. I'm m more sensitive to it than ever before and although I've now cleanedy carpets twice I cannot get rid of the smell and it's driving me crazy so I am in desperate need of help! What takes the smell away?
