belle's ears have a strong unpleasant odor and she scratches her at her ears. my daughter is going to take her to the vet next week. Does this sound like an infection or allergy? Lisa says she's noticed that odor since she got belle last August but says it's become stronger lately. She's been seen by a vet for routine care and nothing has been noted. Her ears look clean, the part that's visible. There's no visible discharge or debris, the ears look normal. but the odor is foul and strong. i can smell it from a few inches away.
