My dog has smelly ears but no signs of discomfort
My shih tzu is getting kinda old (13 years) and the only symptom that i can see is loss of hearing but this may be normal due to old age. When i flip over her ears, it smells. I don't think there's an infection as my dog shows no other symptoms (i.e. scratching or pain). She's her usual self.
Any advice? There ARE some black/dark discolorations on the inner flaps but my vet says its normal yet my groomer says there's an infection.
