Do dogs really smile at us? How can we understand their behavior?

Dogs are loyal friends of human beings, but we know little about dogs. For example, when a dog laughs, does it really express happiness or is it friendly to human beings?

Today, let's have a good analysis.

First of all, the dog's smile generally refers to the shape of the dog when it opens its mouth and exposes its tongue, which is similar to the expression of human smile, so it is mistaken for the dog's smile.

In fact, at this time, the dog is not expressing love, but the dog is radiating heat.

The difference between human and dog's skin is that human has sweat glands, which can dissipate heat through the skin, while dogs don't. The dog's cooling system is exocrine sweat glands, which grow on the meat pads of the dog's four feet and on the nose. However, this heat dissipation area is pitifully small relative to the weight of the dog, and the dog can't cool down quickly through these places.

Fortunately, dogs can also dissipate heat through their tongues. When the dog is tired from heat or play, it will lie on the ground and gasp. Because dogs open their mouths and stick out their tongues in the same shape as when humans smile, humans mistakenly think that dogs are smiling.

But even if it is not a smile, dogs are generally more relaxed at this moment.

So, what actions do dogs show when they are happy?

If you have a dog, you will know that the moment you come home is the most exciting moment for the dog. At this time, it will wag its tail at you quickly, run around excitedly, or circle around you, or even pounce on you.

If you listen carefully, you will hear its coquetry.

This kind of moment is a happy moment for dogs, and these actions are often considered as the performance of happiness and excitement.

If your dog will turn his stomach to you, it means that the dog trusts you completely.

In nature, the dog's stomach is the most fragile part and the most deadly part. Dogs rarely turn their bellies to each other when dealing with other dogs (if they meet an upturned dog, it means they give in to each other). So, if your dog touches you and it turns over, it shows that it trusts you without reservation.

In addition, when two dogs meet, don't let them meet head-on.

In nature, when dogs want to approach each other, they will quietly approach each other through the side, sniff each other, establish ranks or make friends; But when two dogs meet head-on, it means they are enemies. They won't smell each other and will directly enter the attack.

Also, dogs have a sense of hierarchy, not only in dogs, but also when they get along with people. When dogs get along with their families, they will automatically take competent people as leaders and listen to them, while accommodating people will be regarded as dogs lower than themselves and will not listen to them.

In their view, your rank is lower than it, and you should obey it, not it. So if you want to have a dog, you must establish a good hierarchy with the dog.

Dogs are interested in moving objects, whether they are prey or humans. When you meet a dog, maybe if you don't move, the dog will only look at you tentatively, but if you move, the dog will be inexplicably excited and will chase you. Sometimes the dog will catch up with you and do nothing, but as long as you move, the dog will get excited.
