People have always believed that to know the mood or feelings of a dog, one can observe the dog's tail, and of course, there is nothing wrong with this method. Now, some scientists believe that people can already understand the emotions of dogs by understanding the facial expressions of dogs. This is a very interesting experiment and result. I believe that many dog parents will not express doubts at all.

According to the British Daily Mail report, American psychologist Tina Bloom found a 5-year-old Belgiansheepdog, and used various methods to guide it to make different expressions. As a result, 88%, 70% and 45% of people were able to distinguish its happy, angry and fearful expressions from photos, and this result Published in the journal Behavioural Processes.

Some expressions of the dog are really obvious, especially happy and angry. The front will release positive messages through shining eyes and gentle movements, while the lips Turning over completely to reveal the canine teeth is a classic expression of anger.

And it is worth noting that angry dogs will force their ears diagonally back, while softly sticking them back is a sign of submission, surrender, or joy, which is also very common among dogs. A common form of communication, dogs whose ears have been clipped can easily be mistaken for threats by their peers because their ears are permanently erect.

In addition, dogs also turn their ears back and tuck their tails when feeling uneasy or frightened, and may even tremble or find a place to hide.

Coming back to happiness, many people think that the grinning expression of dogs means they are smiling, but in fact only humans and orangutans use grins to express happiness. Dogs instead grin in response to panic or pain. Also, as long as you open your mouth slightly wider when sticking out your tongue to dissipate heat, the corners of your mouth will naturally tilt back.

Eyes are also easy to use to observe a dog's mood, especially for strangers or dogs, looking directly at the eyes is often a sign of provocation, so someone will warn you not to casually talk to Stray dog meets eyes. However, pet dogs look directly at their owners while wagging their tails, often in a sign of waiting and anticipation.

On the other hand, the eyes are erratic and avoid the line of sight, which means avoiding confrontation. The dog will often have this reaction after doing something that will make the owner angry, and the head will be lowered. And their eyes are rolled up, because they dare not look up at people at this time, and then their ears may also stick back to what they just said. It should be noted, however, that dogs expressing fear of their owners' anger does not mean that they know they have made a mistake.
