I started treating Daisy for ear mites about a week ago because she had some bald spots and scabs on her ears. When I went out to treat her this morning I noticed that she has some blisters inside her ears that are filled with white pus. They don't seem to bother her and they aren't oozing. I popped one to see if it was clear fluid or not. What could this be from? Could it be an allergic reaction from the mite medication? She has never has any other medical issues before. The name on the bottle is Shapley's Original Mane Groom Tail. It's for dogs and horses but the lady at the feed store told me it would work for ear mites in goats.
