dogstears are a type of tear that is secreted from the eyes of pets dogs. The lacrimal gland is an accessory organ of the eye, mainly, under normal circumstances, the lacrimal glands secrete tears to moisten the eyeballs and then enter the nasal cavity through the lacrimal ducts, and will not flow out from the corners of the eyes. Tears will flow from the corners of the eyes. Tears formed over time. So what are the reasons for the dog's tears?

1. Diet

Diet is the most common form of tear stains in dogs One of the reasons is the one that everyone knows the most. Dogs eat salty and people are prone to tear marks. Anyone who has raised dogs for more than 3 months should know this. So in this case, first stop feeding salty dog food or food, and give the dog more water. Try to eat as light as possible

2. Diseases

We all know that dogs with eye problems will produce tears. For example, lacrimal gland inflammation: the lacrimal glands that secrete tears are infected, resulting in abnormal secretion of tears, and the nasolacrimal duct can not clear so many tears, which will cause tears to flow out, and unsightly tear marks will be formed over time. There is also a simpler eye problem that is trichiasis. Trichiasis has been irritating the cornea. This situation will make the dog's eyes feel very uncomfortable, resulting in frequent scratching of the eyes with their forelimbs, so they often see teary eyes. It can also cause very serious tears.

In addition to these, I am afraid that everyone does not know that a blocked nasolacrimal duct can also cause tear marks in dogs. The nasolacrimal duct is inflamed and swollen due to infection, resulting in complete or incomplete blockage of the entire duct, so tears cannot be discharged from the nasolacrimal duct normally, and will naturally overflow, resulting in unsightly tear marks. . Also, when the ear canal is infected by bacteria, viruses, molds, parasites, or the ears are swollen, painful, or itchy, dogs will frequently scratch their ears with their hind feet. The auditory nerve and facial nerve are alternately distributed on the face, which is a very sensitive area. Because the pain in the deep part of the ear canal will extend to the area around the eyes, it will also stimulate the secretion of the lacrimal gland. When too much tears cannot be discharged from the nasolacrimal duct, It will overflow from the corner of the eye near the side of the nose. After a long period of accumulation, the brown tear stains on the hair will become very obvious
