Why do dogs produce abnormal “tears”?
The facial features of dogs are the same as those of humans, in fact, they are all interconnected.
When the dog’s nasolacrimal duct is blocked or swollen and narrowed due to inflammation , the fluid cannot be drained or evaporated through normal channels, and it will flow out of the eye.
Causes of tear streaks

There are some congenital noses Shorter breeds, such as pugs for dogs, bulldogs, Garfields for cats, British Shorthairs, Persians and Chinchillas, are more prone to tear marks.
Because cats and dogs with flat faces have short noses and the curvature of the nasolacrimal duct becomes very large, the amount of tears discharged is limited.
Even normal secretion The amount of tears is also unbearable, which will cause unsightly tear marks or even black eye frames.
Tears due to disease:
1. Ear Infections
Ear canal infections are the most common cause of tear stains in dogs. When the ear canal is infected by bacteria, viruses, fungi, parasites, or the ear is swollen, painful or itchy, it will stimulate the secretion of the lacrimal gland.
When too many tears cannot be discharged from the nasolacrimal duct, the It will overflow from the corner of the eye near the side of the nose.
After a long period of accumulation, brown tear stains on the hair will become very obvious.
2. Entropion
Entropion is the so-called inverted eyelashes, which will cause Eyelashes irritate the cornea all the time.
This situation can make the dog’s eyes very uncomfortable, resulting in frequent scratching of the eyes with the forelimbs, and therefore often see them appear watery, which can also cause very serious problems. of tears.
3. Dacryoadenitis
Main It is because the lacrimal glands that secrete tears are infected and inflamed, resulting in abnormal and large secretion of tears.
The nasolacrimal duct is too late to dredge so many tears, which will lead to the outflow of tears, which will also form unsightly tear marks over time.
4. Conjunctivitis
The dog has teary eyes, is afraid of light, The eyes are red, and there will be a lot of sticky eye mucus.
