Like all dogs, the Dachshund’s ear canal is made up of an initial long vertical segment with an abrupt right-angle turn before reaching the eardrum. And as in all dogs, this design means that moisture and debris can accumulate in that hidden area and cause problems.

More harm is done by overzealous cleaning than by no cleaning at all. But if your Dachshund has gobs of debris, clean it using an ear cleanser from your veterinarian. Go outdoors, quickly, squeeze the cleaner in the ear canal, and gently massage the liquid downward and squish it around. Then stand back and let him shake his head, flinging the sludge all over the place. Don’t try this if the ear is red, swollen, or painful; these call for veterinary attention.

Ear problems are often signaled by head tilt, head shaking, scratching, inflammation, discharge, debris, or even circling to one side. They could be caused by infections, allergies, seborrhea, foreign bodies, or ear mites.

Ear mites are especially common in youngsters. They’re contagious, so separate a dog you suspect of having them from other pets. Signs are head shaking, head tilt, and a dark coffee-ground-like buildup in the ears. They itch like mad, so you need to get right to them. Your veterinarian can prescribe ear drops or newer drug therapies.
