We all know that dogs do not speak like humans, but their tails represent their language. For example, when our dogs see new dog friends, they will smell each other's butts, which can make this a way for them to communicate with each other.

Of course, the dog's tail is not just good-looking, it also has the following functions:

Function 1. Spreading the smell

Dogs usually use the method of smelling the other person's butt to meet new friends. This behavior is because the dog's butt has a special gland that can secrete a special smell that belongs to the dog. In addition, when they wag their tails, they will have a "fan" function, mainly to spread the smell!

Function 2. Help balance

The dog's tail has the function of maintaining its own balance, allowing the dog to walk steadily, and the dog's tail can control the direction when running, bathing or swimming. In addition, when the running stops, it is necessary to shake the tail to help stop smoothly. Most dogs were previously used as hunting dogs, and their tails were very necessary to maintain their own balance to help hunt.

Function 3. Express emotions

In addition to this, the dog's tail is also an important way to express emotions! The movement of the tail is similar to their language. When you are happy, the tail will shake to the right, and when you are afraid, you will clamp the tail. You can also see the dog's personality from these behaviors. In addition, they will also respond when they hear the instructions from their owners, but for what humans say is just a source of sound and a signal, so when communicating with dogs, you should pay attention to the tone and their emotions.
