Quick answer

Ear odor, head shaking, scratching, redness, or discharge can signal an ear infection—but the right treatment depends on what is in the ear and whether the eardrum is intact.

Why this deserves attention

Yeast, bacteria, ear mites, allergies, moisture, foreign material, and narrow ear canals can all contribute. Treating by appearance alone can prolong the problem or make it worse.

Helpful steps at home

  • Use only products your veterinarian has recommended for that pet.
  • Keep swimming and bathing water out of irritated ears.
  • Finish prescribed medication exactly as directed and attend rechecks.

When to call sooner: Seek prompt care if your pet cries when the ear is touched, has a head tilt, loses balance, or develops facial swelling.

Make the appointment more useful

Tell the team about swimming, allergies, previous infections, and every product already used.

Common question

Can I use leftover ear drops?

No. Different ear problems need different medicines, and some products are unsafe when the eardrum is damaged.

Can I treat an ear infection with OTC drops?

A veterinary exam helps distinguish causes and assess the eardrum before treatment.

Why do infections recur?

Underlying allergy, moisture, anatomy and incomplete resolution can contribute.

Are ear mites the same as infection?

No. Mites are parasites; secondary inflammation or infection can occur.
