Shih Tzu Eye Problems
Shih Tzus have large, prominent eyes that are more exposed to hair, dust, scratches, dryness, and accidental trauma than the eyes of many longer-muzzled breeds. A watery eye may be minor, but squinting, cloudiness, marked redness, sudden discharge, or reluctance to open the eye can signal pain and should not be watched for several days at home.
The most useful response is to notice which eye is affected, when the change began, whether the dog is rubbing the face, and whether vision or behavior has changed. Eye problems can worsen quickly, so prompt veterinary assessment is often safer than trying leftover drops or repeated cleaning.
Changes That Can Wait for a Routine Call
- Mild tear staining without pain
- Small amounts of clear discharge after sleep
- Hair beginning to brush the eye
- Gradual cosmetic staining with normal behavior
Changes That Need Prompt Care
- Squinting or holding an eye closed
- Cloudiness, blue haze, or a visible spot
- Yellow, green, or bloody discharge
- Sudden redness, swelling, or trauma
- Bumping into objects or acting unable to see
Why Shih Tzu Eyes Need Extra Protection
The breed’s facial shape leaves the eyes relatively exposed. Long facial hair can rub the surface, rough play can cause scratches, and dry-eye conditions can reduce the protective tear film. Even a small corneal injury can be painful and may deepen if treatment is delayed.
Keep facial hair trimmed or secured so it does not sweep across the eye. Avoid letting the dog push through thorny plants, tall stiff grass, or clutter where sharp edges are at eye level. During play with larger dogs or young children, supervise closely because a paw or toy can strike the face.
Common Eye Concerns
- Corneal ulcer
- A scratch or defect on the clear surface of the eye. Squinting, tearing, redness, and light sensitivity are common.
- Dry eye
- Inadequate tears can cause thick discharge, redness, discomfort, and repeated surface damage.
- Cherry eye
- A gland at the inner corner protrudes as a pink or red bulge. It needs veterinary evaluation rather than being pushed back repeatedly.
- Hair irritation
- Facial hair or lashes may rub the surface and create chronic tearing or pain.
- Trauma
- A scratch, blunt impact, bite, or foreign material can damage the eye even when the injury is not obvious.
What to Record Before the Appointment
- Which eye is affected and whether both look different.
- The time the change began and whether it was sudden.
- Any recent grooming, play, outdoor activity, or possible injury.
- The color and thickness of discharge.
- Whether the dog is rubbing, squinting, hiding, or avoiding light.
- Any medication already used, including old prescriptions.
What Not to Put in the Eye
Do not use human redness-relief drops, peroxide, essential oils, homemade mixtures, or leftover prescription medication. Some eye medicines are unsafe when an ulcer is present, and old bottles can be contaminated. Clean only the surrounding hair with a soft damp cloth unless a veterinarian has given different instructions.
Daily Eye-Care Routine
Check both eyes in good light once a day. The surfaces should look clear, the eyelids should open comfortably, and the dog should not be rubbing the face. Wipe moisture from the hair beneath the eyes without touching the eye itself, and keep the face dry enough to prevent skin irritation.
Eye care should be especially careful after grooming, outdoor activity, or rough play. A dog with diagnosed dry eye or another chronic condition needs medication on the exact schedule prescribed; missed doses can allow symptoms to return quickly.
Shih Tzu Eye Questions
Are tear stains an eye emergency?
Staining alone is usually not urgent, but new pain, squinting, cloudiness, swelling, or colored discharge should be evaluated promptly.
Can I flush something from the eye?
Call a veterinarian for guidance. Foreign material can scratch the cornea, and forceful flushing or pulling may worsen the injury.
Why does one eye water more than the other?
One-sided tearing can result from hair irritation, a blocked drainage path, a scratch, infection, or another local problem. Persistent asymmetry deserves an examination.
