Update to my post on July 23:
I first did the Manuka honey, Tumeric and vitamin C but it did not work.
I then did Echinacea and Goldenseal 225/225 mg. I gave it to her for 2 weeks, along with 2,000 mg of vitamin c twice a day.
At the end of the first week, her discharge stopped but I kept on for another week. At the end of the second week, she was completely healed. I had her spayed 3 weeks later so it doesn't reoccur.
I would recommend Echinacea and Goldenseal 225/225 mg if the first remedy does not work for you.
Thank you for this site, my girl is healthy and recovering from her spay surgery.
