The tears are heavy. I believe many dog owners have encountered such problems. Since there are tears, the dog will always cry, right? So is this the truth?

First of all, scientifically speaking, dogs have the basic organ of crying, that is, the tear glands. Their lacrimal glands produce liquid, which remains around the dog's eyes, forming tears. And this liquid can be said to be tears.

Like humans, this liquid has two main functions: basic tears—wet eyes; reflected tears—isolate foreign objects and dirty things.

The tears we talk about basically come from the above two functions.

The dog's eyes are dry, and it is a little wet; the dog's eyes are dusty, and it is a little wet, and it is a little wet.

But when we talk about whether dogs will shed tears like humans, what we are more talking about is whether dogs can shed emotional tears? This is also the third function of human tears - expressing emotions.

Dogs express sad emotions such as pain, pain and sympathy through crying? In this regard, scientists have also done a lot of different research, and no key proof of tears related to emotions has been found, but this does not mean that dogs are indifferent and ruthless. They just experience and express these emotions in different ways. For example:

whimper:

The dog whimpered and wailed. Generally speaking, there are two situations. One is to express pain: "Master, you stepped on me."

Or it may express feelings such as dissatisfaction, anger, sadness, helplessness, etc.: "Master, I want to go out to play, Master, I will play with me" and so on.

Physical contact:

Dogs also use physical contact to express emotions, including sad emotions and happy emotions. They will also react to human emotions, which may be why the golden retriever is called "Big Warm Man".

So, in general, dogs may not shed tears like humans, but the feelings they convey to us are really and profound~ This may be why people like dogs so much~
