If I remember correctly, Fuyu's face has been dirty since they got her in early Feb, they took her to the vet and she had moist dermatitis. She had hay stuck in her teeth so her mouth was cleaned, they got the dirty fur trimmed off, and she was on antibiotics, vitamins, and sterile eye drops. So I think that's why she was so dirty.
I am so sorry for your loss

I've read your threads and I can tell you always tried to do the best you can for her.
