Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bety! Bety sounds sick and should see a Vet. Not eating for 4-5 days can mean a lot of things. The raised third eyelids could mean her eyes hurt. A common reason for a dogs eyes to hurt and also not feel well is uveitis. The phrase the “eyes are the windows to the soul” applies here as uveitis can be a symptom of or secondary to systemic disease. Because Bety is intact and not spayed an infected uterus (pyometra) is a very valid concern and is life threatening. She could have a tick borne disease, leptospirosis, cancer, kidney or liver disease or a fever from many other causes. I hope this helps and I wish Bety the best!
