Shih Tzu Ear Infections
Ear infections can make a Shih Tzu miserable long before the ear looks dramatically abnormal. Repeated head shaking, scratching, odor, redness, tenderness, or dark discharge may indicate inflammation caused by yeast, bacteria, allergies, trapped moisture, excess wax, or a foreign object. Because the ear canal cannot be evaluated safely from the outside alone, persistent symptoms deserve veterinary examination rather than repeated home cleaning.
Routine ear care should keep the outer ear clean and dry without irritating the canal. More cleaning is not always better. Aggressive wiping, cotton swabs, peroxide, alcohol, and leftover medication can worsen pain or hide important clues.
Routine Ear Care
- The ear has little odor and no obvious pain.
- Only the visible outer folds are gently wiped.
- A veterinarian-approved cleaner is used when needed.
- The ear is dried after bathing or swimming.
Signs of an Ear Problem
- Repeated head shaking or one-sided scratching
- Strong odor, redness, swelling, or discharge
- Pain when the ear or nearby cheek is touched
- Head tilt, imbalance, or sudden reluctance to move
Why Shih Tzu Ears Become Inflamed
The folded ear flap can reduce airflow and hold moisture after bathing. Hair and wax may also trap debris, but visible hair alone does not prove that plucking is needed. Allergies are a common reason infections return, especially when ear trouble appears with paw licking, itchy skin, or seasonal flare-ups.
Yeast and bacteria normally live on skin in small numbers. When the ear environment becomes warm, damp, irritated, or inflamed, those organisms can multiply. A veterinarian may examine a sample under a microscope so treatment matches what is actually present.
Safe Steps Before the Appointment
- Note when the symptoms began and whether one or both ears are affected.
- Photograph visible redness or discharge before cleaning.
- Keep the ear dry and prevent vigorous scratching when possible.
- Do not place medication, oil, vinegar, peroxide, or alcohol in the canal.
- Bring the names of any previous ear products or prescriptions.
- Seek prompt care for severe pain, swelling, head tilt, or balance changes.
Cleaning an Otherwise Comfortable Ear
Use only a product recommended for dogs and follow its directions. Apply the cleaner at the canal opening without forcing the bottle tip inside, massage the base of the ear gently, allow the dog to shake, and wipe away material that reaches the outer folds. Stop if the dog cries, pulls away sharply, or the ear appears very inflamed.
Cleaning frequency should be based on the individual dog. Some Shih Tzus need occasional cleaning after baths; others need very little. A dog with repeated infections needs a prevention plan based on the underlying cause, not simply a more frequent cleaning schedule.
Preventing Recurrence
Finish prescribed medication for the full recommended period and attend rechecks when requested. The ear can look better before infection and inflammation have fully resolved. Keep grooming products out of the canal, dry the ears after bathing, and discuss allergies, narrow canals, heavy wax production, or chronic skin disease when infections recur.
Ear-Infection Questions
Can I use cotton swabs?
Use them only on the easily visible outer folds, never deep in the canal. They can push debris inward or injure painful tissue.
Should ear hair be plucked?
Not automatically. Some dogs become more irritated after plucking. Ask the veterinarian or groomer what is appropriate for the individual ear.
Why does the infection keep returning?
Incomplete treatment, allergies, moisture, canal anatomy, resistant organisms, or an untreated underlying skin problem can all contribute.
