Why do tear stains form?

That’s because dog tears contain a chemical called porphyrin. If the tear stains or eye feces are not cleaned in time, the porphyrin will gradually oxidize in the air. Then the soaked hair under the inner corners of the dog's eyes will have rust-like traces, which are what we call tear stains. Some pets with lighter coats will have more obvious tear stains. Although tear stains themselves are not a serious problem, they will only make the dogs look more pitiful. But if this problem occurs for a long time, it may indicate to you the existence of some dog eye problems...

What are the causes of tears in dogs’ eyes

Ear canal infection:

When the ear canal is infected by bacteria, viruses, parasites, or the ears are swollen, painful, or itchy, it will cause the dog to frequently itchy and scratch the ears with its hind feet. Many people will doubt that the tear stains in the eyes are related to the ears. In fact, the ears and the tear stains in the eyes are closely related. Because the auditory nerves are distributed on the face, the itching in the ears will be transmitted to the face and around the eyes, stimulating the bursting of tears.

Improper grooming:

Facial hair on dogs can cause eye infections or irritate eye nerves. Some dog owners love beauty and often take their dogs to trim the fur on their faces or heads. However, some beauty shops trim the fur too short during the grooming process. The hair around the eyes will irritate the eyes during the growth process; If the hair is not shaved cleanly during the grooming process, the short hair left behind will get stuck in the eyes and cause the dog to shed tears. Over time, tear stains will be left around the eyes.

Inverted eyelashes:

As we all know, normal human (dog) eyelashes grow from the inside out, while eyelashes grow from the outside in. These long eyelashes will always irritate the cornea, making the dog's eyes very uncomfortable. They can pierce the inside of the eye and stimulate tears in the dog. On top of that, they can cause inflammation, swelling, etc. in the eyes, which can make them cry all day long, and the same thing can happen. It can cause very severe tears.

Eye inflammation:

On the one hand, it is caused by the inverted eyelashes mentioned above; on the other hand, it is eye inflammation caused by excessive heat.

Nasolacrimal duct obstruction:

If the nasolacrimal duct is blocked and the tear duct is stimulated for a long time, it will become narrow and tears will overflow.

Unreasonable diet:

If the dog often eats salty food or buys dog food or lacks vitamins, it will also cause tear stains in the dog.
