在日常生活，宠物经常会看到猫咪狗狗会流眼泪，具体的原因是什么却不是很清楚，其实导致猫咪狗狗流眼泪的原因有很多，下面作为多年铲屎官的皮总就为大家介绍常见的六个原因。
1: Ear canal infection.
许多人听到这会不免会怀疑眼睛的泪痕，究竟与耳朵有什么关系，其实啊，这当中的关系可大着很，而且此项也是造成猫咪狗狗泪痕最常见的原因。
When the ear canal is infected by bacteria, viruses, mold, parasites, or the ears are swollen, painful, and itchy, it will cause cats and dogs to frequently scratch their ears with their back feet. Because the auditory nerves and facial nerves are intertwined on the face, it is a very sensitive area. The pain in the deep ear canal will extend to the surroundings of the eyes and will also stimulate the secretion of the tear glands. When too much tears cannot be discharged from the nasolar duct, it will overflow from the corner of the eye near the nose. After a long period of accumulation, the brown tear stains on the hair will appear very obvious.
治疗方法：可以请医生诊断是何种原因造成耳道感染，再选择正确的治疗方式，切莫自行乱买耳药治疗，因而导致耳病出现抗药性，更难治疗耳朵方便的病情。 After the treatment of ear canal disease is completed, tears will no longer be secreted vigorously. At this time, the tears will disappear automatically.
2: Nasolac duct is blocked.
因为猫咪狗狗鼻泪管遭受感染而出现发炎肿胀的情况，造成整个管道完全堵塞或是不完全堵塞的情形，于是眼泪也就无法正常从鼻泪管排出，自然就会外溢出，进而也就形成难看的泪痕。
治疗方法：一般来说，兽医会建议采用抗生素来进行治疗，再加上实行通畅鼻泪管的小手术，应该对此疾病会有所改善;此项治疗方法和次数会依照症状程度的不同，或许需要数回合疏通鼻泪管，才能达到解决鼻泪管堵塞的问题。
3: Eyelid inversion.
猫咪狗狗的眼睑内翻也就是所谓的睫毛倒插的情况，会造成睫毛一直刺激角膜，这种情形会让狗狗眼睛感到非常不舒服，进而频频用前肢搔抓眼部，也因此常会看见它们呈现眼泪汪汪的样子，同样也会造成非常严重的泪痕。
Treatment method: Treatment of eyelid inversion usually involves surgery to solve this problem, which is commonly known as "double eyelid cutting", and the part of the eyelash follicles can be effectively solved.
IV: Dracoagitis.
主要是因为分泌泪水的泪腺遭受感染，造成泪液不正常大量分泌，鼻泪管又来不及疏通那么多的泪水，因而就会导致眼泪外流，久而久之也会形成难看的泪痕。
Treatment method: The common method is to use medication to control the treatment period, which may vary from five days to four weeks.
V: Genetic problems.
Primary excessive tears in cats and dogs is a hereditary disease. Tears are often secreted too much, which can easily cause tears.
6: Special breeds of dogs and cats.
这种现象通常出现在短鼻的犬种(例如巴哥、西施、日本狆犬)或扁脸的猫(例如波斯、金吉拉)，因为这样的外型狗狗和猫咪，会让鼻泪管曲度变得很大，所以排出泪水的量有限，即使是正常的分泌泪水量也无法负荷，就会造成难看泪痕甚至黑眼框。
