Typically with ear mites, it will affect both ears. They also look like coffee grinds. The only way to say exactly what it is, is to look at the discharge from the ear under a microscope. If this is done you can actually see the ears mites walk around. To see if it is bacteria and yeast the veterinarian will have to stain the slide to determine. Then appropriate treatment can be given. Thank you for using Petco Pet Education Center, formerly Petcoach.
