Hello all. My dog apparently cut her foot outside and I didn't notice it. She always climbs on the back of our couch. I didn't notice anything was amiss until I saw blood on my couch. Well when I noticed it I tended to my dogs foot, and she is better now. However my tan microfiber couch still has a blood stain on it. I used rubbing alcohol as has been suggested in the past when I got ink on my couch. (I obviously tend to not be the most careful person alive) Well the alcohol worked for the ink like a charm. However with the blood it took most of it out, but left a hint of the blood left behind. Any clue what I should try to get it out??
