EE hasn't 'officially' been diagnosed nor has bloodwork been a strong indicator of such. Biopsy has been suggested, however, I do not feel completely comfortable with surgery since nothing points strongly to EE right now. Food allergy is/has been suspected, which, I believe, is where the idea of EE (allergy induced) came from. I've read that Ivermectin has been used to treat EE, hence, my question. The veterinarian prefers to go in and biopsy tissue, but I'd like to see if there's any response to Ivermectin first. The veterinarian seemed uncertain regarding its use if certain conditions, known or unknown, were to exist. I now plan to try the Ivermectin first. Thanks for your time and for answering my question.
