Shih Tzu Eye Discharge
Eye discharge in a Shih Tzu can range from ordinary clear tearing to a sign of pain, infection, dry eye, injury, eyelid trouble, or blocked drainage. Because the breed’s eyes are prominent and facial hair grows close to the surface, small changes deserve careful attention.
Color alone does not provide a diagnosis. The most useful clues are whether one or both eyes are affected, whether the eye is painful or cloudy, how quickly the discharge appeared, and whether the dog is squinting, rubbing, or avoiding light.
Usually Less Urgent
- Small amount of clear tearing in both eyes
- No redness, squinting, swelling, or cloudiness
- Dog is comfortable and acting normally
- Discharge clears with gentle routine cleaning
Needs Prompt Attention
- One-sided or sudden discharge
- Yellow, green, bloody, or thick mucus
- Squinting, rubbing, pain, or light sensitivity
- Cloudy, blue, swollen, or injured-looking eye
Clean the Face Without Irritating the Eye
Use a soft clean cloth or pad dampened with warm water to loosen debris on the hair. Wipe away from the eye and use a separate clean area for each eye. Do not pull hardened crust from tender skin, scrub the eyelids, or allow grooming products to run into the eye.
Keep facial hair trimmed or secured so it does not rub the surface. If hair appears to be touching the eye, address the grooming problem promptly rather than repeatedly wiping the resulting discharge.
Record These Details
- Which eye is affected.
- Color, thickness, odor, and amount.
- Whether the eye is red, cloudy, swollen, or partly closed.
- Whether the dog is rubbing the face or avoiding light.
- Recent grooming, outdoor exposure, injury, or product use.
- Current eye medications and missed doses.
Why Shih Tzus May Develop Discharge
Clear overflow can occur when tears do not drain normally or facial anatomy keeps the hair damp. Dry eye may create thick, sticky mucus because the tear film is inadequate. Infection, corneal scratches, ulcers, foreign material, eyelid abnormalities, and inflammation can produce similar-looking discharge.
A veterinarian may examine the cornea, measure tear production, check eye pressure, and look beneath the eyelids. These tests matter because a medication that is safe for one condition can be harmful in another.
Avoid Leftover or Human Eye Medication
Do not use redness-relief drops, steroid drops, antibiotic ointment left from a previous problem, or homemade rinses unless a veterinarian directs you. Steroids can worsen a corneal ulcer, and an old bottle may be contaminated or inappropriate for the current condition.
Eye-Discharge Questions
Is brown staining the same as eye discharge?
Staining is pigment left on damp hair, while discharge describes the fluid or mucus coming from the eye. The two may occur together but are not identical.
Can allergies cause watery eyes?
They can contribute, but painful eye disease must be ruled out when tearing is sudden, one-sided, or accompanied by squinting or redness.
When should I seek same-day care?
Seek prompt care for pain, squinting, cloudiness, injury, marked redness, thick colored discharge, or a rapidly changing eye.
