I never got an answer. Biopsy, skin scraping, and fungal culture were all normal. No testing for thyroid and cushings b/c vet thought it was unnecessary. But Ellie doesn't look like a doggie with those types of problems. Anyway, I was told it would be okay to hold off on the testing that we did, but I wanted an answer. Well, we got no answer from them, but it started growing back.
Enzymes seemed to help, but can't be sure. Thinking she may have had some protein malnutrition or something going on (not absorbing it right).
