GASP! Some put hair remover on their ears? Wow.Man I hope that she didn't use hair remover in his ears!! I had this happen to Harry one time I took him to get a groom and they use liquid hair remover to get the hair out of his ears! I was so pissed off I should have chewed them out but I just never went back there. He ended up with an ear infection and needed antibiotics. Since then I've never allowed hair pulling in the ears and he hasn't had problems with them.
Are the ears pink or red? If so it may have burned him....I would contact the groomer and ask them about it.
