Chihuahua
Often we think that dogs tuck their tails because they feel scared, but what is the reason for this?
It turns out that the reason why dogs tuck their tails is not the tail itself, but the bottom of the tail. If the tail is hung down and firmly clamped in the middle of the hind legs, a timid dog can effectively block the passage from it. The breath signal emitted from the anal area. We know that dogs living in the wilderness have a strict ranking relationship, and tail-pinching has become an important signal, a sign of humility for the weak in front of the strong.
Therefore, when we see a dog pinching its tail in life, we can understand that it means that when it encounters an enemy, it becomes timid, frightened, and wants to run away. The main function of the dog's tail is undoubtedly a signal to control the smell, but as an important visual signal, it should not be underestimated.
