Shih Tzu Tear Stain Care Guide | Prevention & At-Home Coat Care

A Shih Tzu's round eyes and white coat are the epitome of adorable—but the reddish-brown tear stains below their eyes are a common concern for many owners. Due to their short muzzle (brachycephalic structure), shallow eye sockets, and abundant facial hair, Shih Tzus are prone to excessive tearing or poor tear drainage, leading to easy staining. The good news: by understanding the causes and maintaining consistent care, you can reduce tear stains and keep the eye area clean and bright.

01Why Shih Tzus Are Prone to Tear Stains

Shih Tzus are a brachycephalic (short-headed) breed, meaning their short nose and muzzle create a skull structure where the eyes protrude and the eye sockets are shallow. This often results in narrow or curved tear ducts (nasolacrimal ducts), preventing tears from draining properly through the nose and causing overflow onto the face.

Additionally, Shih Tzus have a long, dense double coat that covers the eye area. Hair can irritate the eyeball, and tears trapped in the fur create an ideal environment for bacteria and yeast to thrive. Porphyrin pigments in tears oxidize on the coat, causing reddish or brown discoloration that is especially noticeable on lighter-colored Shih Tzus.

Beyond genetic structure, factors like allergies, entropion (inward-rolling eyelids), hair irritation around the eyes, diet, and environmental triggers can also increase tear production, so comprehensive observation is important.

02Daily Tear Stain Prevention Routine

The key to tear stain management is consistent daily care. Morning and evening, use clean gauze or a soft cotton pad dampened with lukewarm water to gently wipe from the inner corner of the eye outward. Avoid rubbing or applying pressure, and remove tears before they dry—this is the first step in preventing staining.

If hair around the eyes is long, it can irritate the eyeball, so regularly trim the hair around the eye area to improve visibility and reduce irritation. When getting a round cut or teddy bear cut at the groomer, ask them to tidy the eye area as well.

If tears pool or the area stays damp, bacterial and yeast growth accelerates, so it's crucial to completely dry the fur around the eyes after cleaning. Use a hair dryer on a cool, low setting or gently blot with absorbent gauze to remove moisture.

03Checking Diet and Environmental Factors

Some Shih Tzus may experience increased tearing in response to specific proteins or artificial additives in their food. Many owners report reduced tear production after switching to a hypoallergenic diet (hydrolyzed or single-protein formulas), so consider a 4–6 week feeding trial after consulting your veterinarian.

Indoor environment matters too. High levels of dust, pollen, and dust mites can trigger allergic conjunctivitis and increase tearing. Use an air purifier, wash bedding frequently, and avoid strong fragrances or cigarette smoke.

Water bowls are also a checkpoint. Plastic bowls harbor bacteria easily, so switch to stainless steel or ceramic and wash them daily.

04Managing Existing Stains

Stained fur won't turn white overnight. Because porphyrin pigments have already penetrated the hair, the surest approach is to continue preventive care until new, clean hair grows in.

Avoid harsh bleaching or chemical products on stained areas, as they risk skin irritation and eye damage. Instead, use a gentle, breed-safe cleanser daily to prevent new staining and gradually lighten existing marks.

ANIBETTER's ANITOK Hair is formulated with mild ingredients for at-home eye area and coat care, gentle enough for daily use on sensitive areas like a Shih Tzu's face. Always thoroughly dry the area after product use.

Trimming stained hair short during grooming gives a cleaner appearance, and newly grown hair can stay pristine with consistent care.

05Eye Health Check — Identifying Structural Issues

Shih Tzus are predisposed to entropion (eyelashes rolling inward), nasolacrimal duct obstruction, and corneal ulcers. If tearing is excessive or occurs predominantly in one eye, suspect a structural or medical cause.

Regular ophthalmic exams can confirm tear duct patency, and flushing or minor procedures may help. Severe entropion may require surgical correction—consult your veterinarian.

If redness, increased discharge, frequent pawing at the eye, or difficulty opening the eye occur, conjunctivitis or corneal damage may be present—seek veterinary care immediately.

06Long-Term Care Tips and Owner Mindset

Tear stains won't vanish overnight, so at least 2–3 months of consistent at-home care is necessary. Establishing a routine at the same time each day reduces stress for both you and your dog.

Shih Tzus are generally gentle and people-oriented, but they can be sensitive about face handling. Start young and use positive reinforcement—praise and treats—to make care time enjoyable.

Some staining may be difficult to fully eliminate due to genetics or individual traits. Rather than aiming for perfect white fur, focus on maintaining hygienic, healthy skin and eyes, and prioritize your dog's overall well-being.
