What are the living habits of puppies?

Happy expression: The dog wags its tail vigorously and jumps high, which is the most common expression.

Sometimes dogs also "laugh", showing wrinkles on their noses, their upper lips pulled open, their teeth exposed, their eyes closed slightly, their eyes gentle, their ears extended backward, their mouths slightly opened, their noses snorted, their bodies twisted slightly, their fur was smooth and erect, and their tails swayed slightly, approaching people.

Expression when angry: The facial expression of a dog when angry is almost the same as that when "laughing". Nose raised, upper lip pulled open, teeth exposed. The difference is that the eyes are round, the eyes are sharp and the ears are straight and oblique.

Generally, the mouth does not open, making a threatening sound, stamping your feet hard, your body is stiff, your coat is erect, your tail is steep or straight, and you keep a certain distance from people. If your forelimbs are down and your body leans back, it means you are going to attack.
