<h1 class= "pgc-h-arrow-right" > the role of a dog's tail</h1>
The tail is a very important part of the dog. The tail can help them stay balanced. When running, jumping and turning, the dog's tail will act as a balance. Even dogs with short or docked tails can maintain balance, and if a dog's tail is injured or partially amputated, it is likely to lose its sense of balance and their motor skills will change. In addition, when swimming, dogs can also use their tails as a rudder in the water.

The tail is also a social tool for dogs, and they can express their current mood to their partners through their tails. In general, when dogs are in a relaxed mood, their tails will droop to the ankle or root of the foot. Some large dogs have tails between their thighs. When the dog's mood fluctuates, the speed and direction of the tail swing will also change.
1. Tail swinging high and low
When the dog is confident and wants to show superiority to the dogs around it, the dog will raise its tail. This is because the leader of the wolf pack will generally be at the front of the group, while the wolves behind will line up marked by the leader's high tail. Therefore, when a dog is considered a leader in the dog herd, it will be very proud. Therefore, it will hold its tail high to show its superiority.
Conversely, if the dog droops its tail, it means that it feels alert, uneasy, and afraid. The further down the dog's negativity becomes, the more severe it becomes, and if its tail is sandwiched between its legs, it must be afraid. When some dogs feel uneasy and frightened, they will clamp their tails to block the odor signal emanating from the area and not be discovered by the enemy. There are also some dogs that develop aggressive behavior because of fear and uneasiness.
2. Tail swing horizontally
When the dog smells a strange smell, hears a strange sound, or feels that someone is approaching in the distance, the dog's tail will be horizontal. Although there is no strong sense of aggression, the tail will also remain horizontal when alert to strangers. Whether positive or negative, when a dog is interested in something, its tail remains level.
3. Tail swing speed
Many people may think that dogs wag their tails because of excitement. But in fact, dogs wagging their tails are not necessarily representative of friendship. When the dog's tail swings sharply to the right, and the butt swings with it, and even the tail is constantly rotating, it means that it is very happy. If you notice that your dog's hind foot muscles are still tight, then you should not get any closer to your dog, because it may be nervous or hostile at this time.
If you see a dog's tail slowly wagging, it may mean that the dog is thinking. Relatively speaking, slow tail wagging also means that the dog is not very friendly. In order to avoid being bitten, you can observe the dog's eyes, ear movements, personality, etc., and then judge what kind of state the dog is in according to the surrounding environment.
4. Tail swinging from side to side
Recently, italian scholars have studied the expression of feelings about dogs. Studies have shown that the brains of people and dogs are separated from the left and right, with the left brain associated with positive emotions and the right brain associated with negative emotions. The mapping movements of the left and right brains and the left and right bodies are reversed, with the left brain acting mainly on the right side of the body and the right brain acting mainly on the left side of the body.
Therefore, when the dog's tail is wagging to the right, it means that it is very excited and happy, which is a positive emotion. When the tail is obviously swinging to the left, it should be that it encounters something uncertain, or something that makes the dog feel sad, such as you playing with other dogs in front of your dog. So if you want to know how the dog is feeling, you can refer to which side of its tail is swinging and make a judgment.
<h1 class="pgc-h-arrow-right" > dog may have been injured if he didn't wag his tail</h1>
The dog's tail is connected to the spine, consisting of 5-20 vertebrae, and there are a large number of blood vessels and nerves distributed on the tail. Sometimes the tail may be fractured or dislocated due to collision or being stepped on, and excessive waving may also lead to "happy tail syndrome". Happy tail syndrome generally occurs in dogs with long tails, and due to repeated impacts of the tail on hard objects such as walls, doors, and furniture, it may cause an open wound to form at the end of the tail.
Sometimes dogs are reluctant to wag their tails because they are unwell or depressed. If you touch its tail and it doesn't like to be touched, it may be injured.
Some large sports dogs, such as Labrador, Golden Retriever, etc., may be over-exercised, resulting in "tail failure to lift". The tail of the sick dog will suddenly be unable to move, and the tail below the root will appear to be hanging down, or the tail 3 or 4 inches below the root will be parallel, and the following part will be weakly drooping. Long-term swimming can easily lead to damage to the dog's tail muscles, temporarily unable to move, and when the temperature is too low, the dog will not lift its tail. The dog's tail does not lift the disease, within two weeks will recover on its own, the owner does not have to worry too much.
