A dog might cry because its eyes are irritated, such as by dust causing watery eyes. Tears can also appear as a sign of sadness or emotional instability in dogs. Additionally, crying in dogs can be related to ingrown eyelashes or excessive or overgrown eye hair.
Why the dog cried
Scientifically, dogs, like humans, have tear glands and the ability to produce tears. When their eyes are irritated, such as by dust, direct sunlight, or wind, they will tear up, which is normal.
Dogs are very intelligent and perceptive, and they are also quite emotional. If a dog is unhappy, it may shed tears or whimper, much like a wronged child. At this time, the owner needs to comfort the dog promptly.
When a dog's eyelashes grow inwards or the hair around its eyes is too thick or long, causing discomfort to its eyes, the dog will involuntarily shed tears, as if it is crying. In this case, the owner needs to help the dog trim its fur.
