Dog friends often complain that their teddy dogs have very serious tear stains. A friend told her that drinking some isatis root can cure the problem. Although isatis root is a panacea, there is no basis for treating tear stains in dogs, which will lead to tear stains. What is the cause of excess? How to clean and remove it?

1. Diet is very important for the control of tear stains. Dogs have very low demand for salt. You can choose food with low salt content. Sometimes changing dog food will have unexpected effects.

2. Infection of the ear canal. When there is a problem with the ear canal, the dog frequently scratches the ear with its hind limbs. The nerves are crisscrossed on the face, making it a very sensitive area. Since the pain deep in the ear canal will extend to around the eyes, it will also stimulate the secretion of tear glands. When this happens, When excessive tears cannot be discharged from the nasolacrimal duct, they will overflow from the corner of the eye near the nose. After a long period of accumulation, brown tear stains on the hair will become very obvious. The best way is to go to a regular pet hospital for diagnosis, remove the cause, and then treat it.

3. Blockage of the nasolacrimal duct. Due to the blockage of the nasolacrimal duct, tears cannot be discharged from the nasolacrimal duct and will naturally overflow outward, forming tear stains over time. Antibiotic treatment will have some effect.

4. Eyelid problems. Abnormal eyelid problems may cause eyelashes to irritate the cornea, causing excessive tears and causing serious tear stains. The fundamental method is surgical treatment. Conservative treatment involves regular eyelash removal.

5. Special breeds of dogs, such as: Myna, Shih Tzu, Bulldog, etc. Because dogs with such an appearance will make the curvature of the nasolacrimal duct become very large, the amount of tears discharged is limited, and even the normal amount of secreted tears cannot be loaded, resulting in unsightly tear stains and even dark circles
