Everything about my dog ​​is fine except that he has a lot of tears and the corners of his eyes are like two sinks. Now the editor of Medical Guide will give you some analysis: The lacrimal gland is an accessory organ of the eye. Its main function is to secrete tears to moisturize the eyeball. Under normal circumstances, the lacrimal gland secretes tears to moisturize the eyeball and then enters the nasal cavity through the nasolacrimal duct and will not flow out from the corner of the eye. However, if foreign bodies, hyperplasia, blockage and inflammation occur, the above situation will occur.

Causes of tear stains

1. Diet

If the food your dog eats has a strong taste, you should pay attention and quickly change it to lighter food with low salt content. It is worth noting that dog food is very important. Sometimes you will find unexpected effects by changing the dog food. In addition, you should give your dog plenty of water to drink.

2. Physical disease

1. Ear canal infection

When many people hear about ear canal infection, they will inevitably have questions. What does tear stains in the eyes have to do with the ears? In fact, the relationship is very close. It is the most common cause of tear stains in dogs.

When the ear canal is infected by bacteria, viruses, molds, parasites, or the ears are swollen, painful, or itchy, it will cause the dog to frequently scratch its ears with its hind legs. The face is a very sensitive area as the auditory nerve and facial nerve are interlaced. The pain in the deep part of the ear canal will extend to around the eyes and stimulate the secretion of lacrimal glands. When too many tears cannot be discharged from the nasolacrimal duct, It will overflow from the corner of the eye near the nose. Over a long period of time, brown tear stains on the hair will become very obvious.

2. Nasolacrimal duct obstruction

When the nasolacrimal duct becomes infected and becomes inflamed and swollen, the entire duct becomes completely blocked or incompletely blocked. As a result, tears cannot be discharged from the nasolacrimal duct normally and will naturally overflow, thus forming unsightly tear stains. .

3. Entropion of eyelids

Entropion of the eyelids, also known as inverted eyelashes, will cause the eyelashes to constantly irritate the cornea. This situation will make the dog's eyes very uncomfortable, leading to frequent scratching of the eyes with the forelimbs. Therefore, they are often seen looking tearful. It will also cause very serious tear stains.

4. Dacryoadenitis

The main reason is that the lacrimal glands that secrete tears are infected, 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 unsightly tear stains over time.

5. Genetic problems

Primary polycythemia is a hereditary disease in which tears are often secreted excessively, thus easily causing tear stains.

3. Genetic factors of special breeds

This kind ofThis phenomenon usually occurs in short-nosed dog breeds, such as Pug, Shih Tzu, and Japanese
