Is it normal for dogs to have ear wax?
Cerumen, what we call earwax, is a normal, natural component of all dog ears. Earwax is secreted by special glands in the ear, and functions to collect dirt, debris, dead cells, microbes, pollen, etc.

Healthy earwax should be a pale, yellowish color. If your dog appears to have dark brown or black earwax or if the earwax looks dirty gray instead of golden, this isn't normal. A noticeable increase in wax build-up can be a sign of a problem as well. A healthy dog's ears should have no smell.
