Dogs don't speak, but every action they make can express their emotions. As a poop collector, if you can read a dog's micro expression, it means you really understand it. Even if you don't understand the owner, it doesn't matter. Now let's take a look at what micro expressions a dog has?

01 Wrinkled nose
If the dog's nose suddenly wrinkles, then the dog is more angry and aggressive. It is best not to approach the dog if it is not its owner at this time.

02 Yawn

Dogs may yawn when feeling anxious or uneasy, usually when feeling external pressure. For example, in a unfamiliar environment or when seeing another dog, yawning is used to release stress and relax their mood. Of course, dogs may also be tired.

03 Sticking out one's tongue
After each exercise, dogs will pant heavily because they are dissipating heat. The soles of their feet secrete sweat glands that can help dissipate heat, but they mainly rely on opening their mouths to breathe and dissipate heat. At this time, dogs will open their mouths slightly or greatly, spit out their tongues, and lower the temperature inside their bodies.
However, sometimes their shortness of breath is a signal of being in a stressful environment, and they may feel nervous or fearful, or extremely excited or excited and may even stick out their tongues.

04 Lick your nose
Dogs usually lick their nose to clean their lips after seeing food or finishing their meal, and frequent nose licking also indicates that they are relaxing themselves. But when the dog is nervous and facing an awkward environment, licking the nose will also occur frequently.

05 Cover your lips tightly
If the dog's mouth is relaxed and slightly open, it indicates that they are not at all alert and are in a relatively relaxed state. If the originally slightly open mouth suddenly closes, it may indicate that the dog suddenly notices something, or something has happened that makes them unhappy and become tense. At this time, the defecator needs to pay attention to their behavior to see if it makes the dog uncomfortable.

06 Eye avoidance
Setting aside and blinking eyes is usually a sign of discomfort in dogs. A common example is that when taking photos, the camera often makes the dog feel uncomfortable, so the dog often turns its gaze to one side and does not look at the camera. Or when the defecator glares at the dog and curses, the dog usually turns its gaze away and looks at the other side to escape. Dogs with flickering eyes may have done something wrong, so they dare not look directly into your eyes to avoid conflicts with you.

07 Pupil enlargement
A dog's eyes may become round, and they may be frightened, scared, or emotionally excited. In these cases, the dog's pupils may also enlarge, and the defecator can observe this change at close range.

08 blink
Blinking a dog at you is also a friendly gesture, which makes them look very cute and easy to get along with. However, sometimes when a dog blinks at you with a nervous expression, it is likely that the dog is afraid.
