on my off-white LR carpet. Two great big piles of brown gunk. I scraped up as much as I could and used everything I had. Enzyme cleaner did nothing. Oxyclean did nothing except bleach my carpet a little. Finally I put Resolve on it, was supposed to leave it 5 min but I forgot about it until this morning. The stain is gone!

I thought I had used that stuff before without any result. Guess not, or they've changed it.

Giving a cleaner enough time to work is often the answer as to why it does or does not clean easily? Also the hotter the water in a steam extractor makes a big difference there.
The enzyme cleaner especially needs to set and soak into the area and have enough time to work.

Hope your dog is feeling better too?

So glad for you that whatever combination or final product finally did the trick!
