Hi Dr. Mag, I noticed one of our dogs shaking and scratching at their ear tonight. I looked in the ear and it is red and has dark brown ear wax on the outer ear and smells a little musty and sour. The other ear is normal, no smell and no redness. I removed the wax with cotton but do not have ear cleaner. Would I be able to purchase some cleaner from the vet? Or could you recommend one for purchase? This is for Zoey. Thank you!
