What s the matter with dogs loving to add tails, why dogs always hold their tails

There are a lot of fleas on the tail parasites.

Tail clamping has its special role in the dog's body language, why tail clamping is associated with fear, cowardice, humility and status, and cocking the tail is a sign of high status and triumph.

When we see a dog with its tail in our life, we can understand that it has become timid, scared, and wants to run away when it encounters an enemy.

The primary function of the dog's tail clamp is undoubtedly a signal to control the smell, but it is also a secondary visual signal that cannot be ignored.

Let's take a look at the emotional expression of the dog's tail:

The answer lies not in the dog's tail itself, but under the tail.

The dog hangs its tail down and clamps it tightly between its hind legs, and a cowering dog effectively blocks the odor signal emanating from its ** area.

When two high-status dogs meet, they will both their tails high, exposing their ** area for each other to sniff their own scent.

Because the ** area is unique to each dog, indicating its identity of the smell, the tail does not let the smell come out, for the dog is like a person who feels inferior and does not want to show his face.

For dogs living alone in human families, although this expression is not important, as long as a group of dogs live together, the hierarchical relationship is very important, and the tail clip has become an important signal, a sign of humility for the weak in front of the strong.

Undoubtedly, this is especially important in wild wolves.

A low-status wolf will hang its tail when it approaches a higher-ranking wolf, and when it approaches the "head wolf", it must hold its tail tightly between its legs, and will not dare to raise its tail again until it is far away from the "head wolf".

Regarding the display of the tail, there is an interesting difference between family dogs and their wild ancestors.

On all wolf tails there is a special tail gland, located at the lower end of the tail, surrounded by light stiff hairs.

This blackened caudal gland is made up of a group of mutated sebaceous glands that emit odor but do not secrete oil.

Just like the glands, the caudal glands are only associated with odor signals and are located on the outside of the tail.

If the wolf approaches another wolf with its tail between its legs, the smell from its tail gland can still be smelled by the other party, but the smell from it ** is gone.

Without this tail gland, it can be seen that the smell signal of a wolf is much more complex than that of a dog.

Why the dog's tail gland degenerates is still a mystery.

As for the other changes that have always taken place in the process of the evolution of dogs from wolves in 10,000 years, they are all deliberately selected due to human needs, and the result is the so-called purebred dog that we see today.

However, the function of the wolf's tail gland has only recently been discussed, so it is unlikely that it would have been noticed by those who breed new dog breeds centuries ago.

Still, it's safe to assume that the tail gland disappeared in dogs very early, as all dogs now have no tail glands.

Regarding the cocked and hanging tails of dogs and wolves, their primary function is undoubtedly a signal to control smell, but as a secondary visual signal it is also not negligible.
