1. Tear Duct Issues: Shih Tzus are prone to having blocked tear ducts, leading to excess tear production. These tears contain a pigment called porphyrin, which oxidizes and turns brown when exposed to air.
2. Diet: A diet high in certain proteins or iron can also contribute to tear staining.
3. Allergies: Allergies can also cause increased tear production and exacerbate the problem.
Here are some effective ways to manage tear staining in Shih Tzus:
1. Clean Regularly:
* Use a tear stain remover specifically formulated for dogs. These products usually contain enzymes that break down the porphyrin.
* Clean the area daily with a soft cloth and warm water. Be gentle around the eyes.
* Avoid using harsh chemicals or bleach, which can irritate the delicate skin.
2. Consider a Diet Change:
* Speak to your vet about switching to a high-quality dog food with limited protein and iron content.
* Offer a balanced diet that includes fresh vegetables and fruits.
3. Address Allergies:
* Identify and eliminate potential allergens, like dust mites, pollen, or certain foods.
* Consider an allergy test with your vet to pinpoint the cause.
4. Professional Help:
* If the problem persists, consult a veterinarian. They can assess the tear ducts and recommend further treatments, such as flushing or surgery.
5. Additional Tips:
* Keep the fur around the eyes trimmed to minimize contact with tear stains.
* Use a humidifier to keep the air moist, as dry air can exacerbate tear staining.
Important Note:
* Never attempt to "bleach" or use harsh chemicals to remove tear stains, as this can damage the skin and cause irritation.
* Always consult your vet if you notice any signs of irritation, redness, or swelling around your Shih Tzu's eyes.
By combining these strategies, you can help keep the fur around your Shih Tzu's eyes looking clean and bright.
