Crusty, Oozing Ear: Yeast or Something Else?
they were oozing yellow.
Please tell me if this looks like a yeast infection or something else.
Yellow oozing and crusting can come from a bacterial infection, yeast, or both, and they can't be told apart reliably from photos. A swab examined under the microscope tells your vet which it is and which drops to use.
Please avoid vinegar on a raw, oozing ear; it can sting and irritate inflamed skin. Keep the area clean and dry, and have your vet check the ear canal and eardrum as well as the crusted skin.
