Please don't take any chances - Simba PROBABLY won't actually bite you - but if I was him and it hurt that much .... I would!
Learn how to do the tape muzzle, it will only be for a few minutes a day and it is a lot, LOT, better than struggling with the fact that your dog was forced into biting you (from his point of view) but he hates his ear treatment which hurts but has to be done to make him better (your point of view).
