I'm sorry, I didn't know your message was here. To answer you, it begins in many ways. Lumpy, red, or black. Then black inside and along the ridges. This worked for me, in this order. I did it in steps, as Victoria gets wild. Day 1: Massage
Epi-Optic ear cleanser (vet) for dogs, cats on inner and outer ear surface, then squirt some down ear canal. Later, bathe with Malaseb Shampoo for dogs(EntirelyPets.com). Leave it on for the entire 10 minutes. ( I shampoo the ears the next day) Keep both products out of eyes. Day 2-3: Foam up the Malaseb Shampoo on on inner and outer ear surface, but not in ear canal. Leave on 10 minutes. Wipe off with wet rag until clean. Repeat every 2 weeks or so until it's gone. If it later comes back, repeat the above. I do the whole cycle 5 times a year. Works for us.
