Pets, like people, have eyes that are easily irritated. If a dog’s eyes shed too many tears, they will easily form tear stains. For dog tear stains, parents can use tear stain cleaning fluid, pet eye drops, or take nutritional supplements for dog eye health care to solve the problem.

Tear stains on dogs are mainly caused by several reasons:

1. The food you eat is salty.

2. Dog breed issues.

3. Hereditary problems.

4. Dacryoadenitis.

5. Other physical diseases: ear canal infection, nasolacrimal duct obstruction, and eyelid entropion.

According to the different situations of dogs with tear stains, different methods can be used to solve them:

1. The food that dogs eat is relatively salty, which will cause more tears. Over time, tear stains will form. You can change the dog's food to a food with a lower salt content or natural food, which can improve the condition of the dog's tear stains.

2. Some long-haired dogs and short-nosed dogs have more tear stains. The hair of long-haired dogs can easily get into the eyes and irritate the eyes, causing excessive tears and irritating the eyes, such as Shih Tzu, Yorkshire Terrier, Maltese, etc. For dogs, the hair around the eyes should be cut off or Let’s make a quick comment. If tear stains have formed, you can use tear stain cleaner to wipe them away. Dogs with short noses will have a large curvature of the nasolacrimal duct, so the amount of tears discharged is limited. Even the normal amount of secreted tears cannot be loaded, and tear stains and even dark eye frames will occur, such as: Dogs, Shih Tzu, etc. usually pay more attention to cleaning their eyes or take some nutritional supplements for dog eye health to improve the tear stains.

3. Primary polytemarism is a hereditary disease. Tears are often secreted excessively, and over time, tear stains will form. For tear stains caused by this hereditary problem, it is usually necessary to clean and care for the dog's eyes or take some nutritional supplements for dog eye health to improve the tear stains.

4. Dacryoadenitis is mainly caused by the infection of the lacrimal glands that secrete tears, resulting in abnormal and large amounts of tear secretion. The nasolacrimal ducts have no time to clear so many tears, which leads to the outflow of tears and the formation of ugly tear stains over time. This This situation can generally be solved with anti-inflammatory pet eye drops.

5. Ear canal infection and nasolacrimal duct obstruction will cause tears to be unable to be discharged from the nasolacrimal duct normally, and will overflow from the corner of the eye near the nose, forming tear stains over time. Entropion of the eyelids means that the eyelashes are inverted and the eyelashes irritate the cornea. The dog's eyes are uncomfortable and he will frequently scratch the eye area with his forelimbs, which can also cause severe tear stains. In these three cases, it is best to go to the pet hospital for diagnosis and then symptomatic treatment.
