Pet Stains on Light Microfiber?

I bought a very light beige microfiber couch and chair (what was I thinking). Then I got a roommate with a dog that laid on the couch and caused a deep dark stain. I have tried microfiber cleaner to get it out to no avail. I also tried an upholstery cleaning machine. It goes away for a little while and then comes right back. Please help me.
