is really important:
1. There is no definite basis to explain that dog tears are directly related to sadness, uncomfortable and other emotions. Dogs usually whimper or whine when they feel sad or painful, and some have physical reactions such as drooping tails and drooping ears.
2. Tears may be caused by over-eating, over-eating, or food poisoning. It may also be caused by eye diseases. Dog owners should pay attention to observation and seek medical attention in time.

People will cry when they are sad, so will pets?
We can see a lot of videos of pets crying on the Internet, especially when the owner has some conditions, some cats and dogs have tears and it looks quite heartbreaking.
In addition to dogs, there are other examples of animals crying, such as cows, seals, and crocodiles. However, some experts have confirmed that the crocodile sheds tears because it has a "salt gland" in its eyes. The salt that it has ingested for a long time from food will be discharged through this salt gland, thus causing the phenomenon of "crocodile tears".
Is the tears of the dog really because of sadness? Or is it because of other conditions?
There is no inevitable connection between dog tears and sad emotions
Judging from the currently available data, there is no definite basis to show that dog tears are directly related to their sadness and uncomfortable emotions.
Studies have shown that the physiological structure of the lacrimal glands of cats and dogs is different from that of humans. The human lacrimal glands connect the eyes, but the lacrimal glands of cats and dogs connect the nose and throat.
Lacrimal glands secrete tears, and then spread to the entire eyeball as dogs and cats blink, and then gather to the punctum, flow along the lacrimal canaliculus to the nasolacrimal duct, and finally reach the nasal cavity.
Simply put, the sequence of the tears of dogs and cats is: lacrimal gland-nasolacrimal duct-nasal cavity.
How do they usually show up when they feel sad or painful?
is generally a whimper or wailing sound, or listlessness on the limbs, such as a drooping tail and drooping ears. Their sadness is not necessarily a "tearful" reaction.
What causes the dog to cry?
ruled out emotional factors, the dog crying is probably due to eating problems, or directly sick.
first look at dietary issues.
1, eating too salty, too good
Dogs eating too salty food will increase the secretion of the lacrimal glands, which will lead to tearing. In addition, too many minerals and impurities in the dog's drinking water, or the dog's food is too good, such as eating offal, will make the dog cry.
Therefore, the owner must pay attention to the dog's diet. Don't give him salty or good food. It is best to match meat and vegetables. Generally, dog food contains 1% of salt. Remember to let the dog drink plenty of water.
2, poisoning by accidental eating
If a dog accidentally eats food contaminated with organophosphate or the carcass of a poisoned animal, or rubs the skin with organophosphate for deworming, it will also cause tears. Generally, this situation will be accompanied by other abnormal symptoms, such as vomiting, diarrhea, muscle tremor, etc. At this time, the shoveling officer must pay attention to it. You must take the dog to the doctor in time.
Let's look at the disease problem again:
1, various ocular inflammations
After a dog's eye is inflamed by bacterial infection, it may cause inflammation such as conjunctivitis and keratitis. Therefore, the shoveling officer should pay more attention to the dog's eye hygiene. If there are signs of inflammation, you can use pet-specific eye drops or chloramphenicol eye drops or chloramphenicol eye ointment to relieve it.
2, eye diseases
, glaucoma and cataracts are also causes of tears in many dogs. The clinical manifestations of these diseases are excessive tearing accompanied by enlarged pupils and no response to light. They generally lead to increased intraocular pressure. If not treated in time, it may lead to blindness. The shit shovel officers should take their dogs for regular inspections.
3. Nasolacrimal duct blockage
Congenital lacrimal duct occlusion, nasolacrimal duct blockage causes ocular secretions to pass through the lacrimal duct to the nose or throat, and can only flow out from the eyes, forming obvious tear marks. There are poodles at home,For pit bulls, pugs and other breeds of dogs, when this happens to the pet and there are no other problems, this problem must be considered.
4, external stimulus
In addition to the above reasons, many unforeseen reasons from the outside world, such as second-hand smoke, dirty air, trichiasis, etc. can also cause the dog to cry. The owner should find a special pet doctor to remove the dog’s eyelashes; strong Light, ultraviolet rays; foreign objects in the eyes when playing can also cause the dog to cry.
5, genetic
In addition, there will be some breeds of dogs because of genetic problems, which will cause them to cry naturally, and tears will appear over time. This situation generally occurs in short-nosed dog breeds, such as pugs, Shih Tzu, bulldogs, and Japanese cruel dogs.
6. Other diseases occur
When dogs catch a cold, canine distemper, small dogs or other diseases, dogs will also shed tears. When accompanied by other symptoms such as fever and vomiting, the pet owner must take the dog to see a doctor in time.
So knock on the blackboard, the point is here. Under normal circumstances, pets will not cry for no reason. It is likely that the body has an abnormality. The veterinarian Xiaoming reminds everyone that if you suddenly find that one day your pet ignores you, or runs into a corner for no reason, and hides in the corner, it doesn’t come out and keeps whimpering, or it’s because they treat you I have caused dissatisfaction with my recent actions, or I am sick. Shovelers must not take it lightly, please pay close attention to their physical and mental conditions.
