We humans will shed tears when we are sad or happy to express our emotions. Crying is a way to vent emotions. We can often see dogs crying. What exactly makes dogs cry?

Eyeworm

Eye worms are white bugs that live in the eyes of dogs. They damage the conjunctiva and cornea, cause conjunctivitis and keratitis, and stimulate the secretion of tears. If there is a secondary bacterial infection, it will be more serious.

Dogs often become extremely restless after being infected, rubbing their eyes against other objects, shaking their heads, and losing appetite.

A dog's eyes suddenly become dull, dim, and cloudy. It bumps into furniture when walking, and appears hesitant when jumping up and down. This may be because of cataracts.

Due to aging, trauma, long-term eye inflammation or genetic problems in dogs, lens metabolism disorders are caused. Because light is blocked by the turbid lens and cannot be projected on the retina, the dog's vision is very blurred after the disease, and it will also be accompanied by tears. Phenomenon.

Eyelid ectropion is an abnormal condition in which the eyelid margin turns outward away from the eyeball. In mild cases, only the eyelid margins leave the eyeball, but the capillary action between the eyelids and the eyeball is destroyed, causing the dog to often shed tears. In severe cases, the entire palpebral conjunctiva of the dog is exposed.

Due to eye discomfort, dogs will often scratch, which will aggravate the ectropion.

Due to the long-term tearing of dogs, serious tear stains in the inner corners of the eyes are caused, and the moisture around the eyes causes skin inflammation.

Severe ectropion often causes incomplete closure of the palpebral fissure, causing the cornea to lose protection, resulting in exposure keratitis and ulcers.

Inverted eyelashes

Trichiasis means that the dog’s eyelashes do not grow along the outside of the eye, but one or two lashes grow into the eye, which always irritates the eyeballs and causes constant tears.

This situation needs to be treated through surgery, which is somewhat similar to human double eyelid surgery. After the surgery, the problem of dogs always crying can be completely solved.

Sick dogs often shed tears, their eyes are afraid of light, they blink frequently, their conjunctiva is congested, and their eye secretions increase.

The biggest danger of abnormal eyelash growth is that it will directly irritate the cornea, causing corneal inflammation and affecting vision.
