Tumours or growths are common in senior dogs. A broad group of space-occupying non-cancerous, benign, and malignant cancers may localise to the ear. Your vet may suggest simple FNAC or biopsy or even imaging including MRI to know the nature and location of tumour. Some tumours/cancers can be treated successfully with chemotherapy, while some may require surgery with or without chemo. Please consult your vet ASAP before it spreads deeper in the ear canal or to other organs.
