Dogs don't wag their tails when they see their owners. Dogs are one of the most common and favorite pets in our lives. Many families also have dogs. In the process of getting along with dogs, we all know the behavior language of dogs. The dogs below don't wag their tails when they meet their owners.
Dogs don't wag their tails when they see their owners.
Second, the owner may have hit it, or even hurt it, leaving a shadow on it.
Third, some dogs can't wag their tails, which may be a congenital bone problem.
Fourth, it may be the dog's personality. Some dogs are fierce and won't go near anyone.
How to understand the wagging of a dog's tail
Dogs often wag their tails to show their friendliness to people. However, a research team from the Biology Department of Victoria University in Canada found that wagging its tail to the left may be a sign that dogs are more friendly and close.
According to the British "Daily Mail" report, the results of this study show that dogs tend to wag their tails to the left when facing strangers of the same kind; However, in the face of human or other animal stimulation, the dog's tail tends to swing to the right.
The researchers made a dog model, which can remotely control its tail to swing from side to side. This model is about the size of a real dog and is wrapped in artificial skin. Subsequently, they filmed the behavioral reactions of more than 500 real dogs when they approached the model.
The results show that when the tail of the dog model swings to the left, most dogs will approach the model without hesitation. When the tail swings to the right, dogs close to the model will become cautious and many dogs will shrink back.
The researchers speculate that it may be that the tail wagging of the model gave some hints to the dogs near it, which made them react completely differently.
Animal psychologist Magford pointed out that previous studies have proved that dogs, like people, have physiological laterality. "If you give the dog instructions or signals, you'd better use your left hand, because dogs tend to look to the left. This is not common in other animals. "
Dog laterality
Regarding the physiological laterality of dogs, Australia has done research before.
Through research, Dr. Macleavy of the University of Sydney found that 65,438+05% dogs are used to using their right paws, 65,438+05% dogs are left-handed, and the remaining 70% dogs have no obvious preference for using their right paws. At the same time, male dogs are left-handed and female dogs are right-handed.
Macleavy believes that the study of laterality will help people to further understand human physiological laterality.
Dogs don't wag their tails when they see their owners.
Recently, Italian scientists found that the direction in which dogs wag their tails can actually reflect their emotions at that time. Swing to the left indicates fear, and swing to the right indicates great excitement.
In the latest issue of Contemporary Biology, Giorgio Veroteguela, a professor and zoologist at Trieste University in Italy, published his latest research results. Giorgio Verotiguela said that wagging a dog's tail is definitely not only an instinct, but also a language.
Although different types of dogs have different tail shapes and sizes, their tail movements can express roughly the same meaning.
In the experiment, researchers found that the direction in which dogs wagged their tails was closely related to their mood at that time. When they are excited or willing to get close to someone or something, they will swing their tails more to the right, and when they feel scared, scared or want to escape, they will swing their tails to the left.
Giorgio Verotiguela said that in the long-term experiment, the researchers * * * selected 30 pet dogs as experimental subjects. Among these pet dogs, 15 is male, and the other 15 is female, all aged between 1 and 6 years old. The researchers first put the dogs in a square box, and then covered them with a layer of black opaque plastic to prevent them from looking out from the inside.
Later, the researchers began to let different people and animals appear on one side of the box. These people and animals are visible to the experimental dogs. These people and animals are dog owners, strangers, a stronger strange dog and a kitten. When these people and animals appeared in the line of sight of the dogs, the direction of their tail wagging at first began to be different and showed certain regularity.
The researchers found that the dog was extremely excited when its owner appeared beside the box. It kept jumping and wagging its tail to the right. When strangers and kittens appear in the dog's sight, the dog will wag its tail to the right, but the swing strength is very different, and the swing strength is gradually decreasing.
When the researchers put a 4-year-old strong male Belgian shepherd into the dog's sight, the experimental dog immediately became very scared and began to wag its tail to the left. When the Belgian shepherd dog left the dog's sight, it gradually returned to normal.
The researchers also found in the experiment that the activity of dog tails is also closely related to their sense of smell and health. The frequency with which a dog wags its tail reflects the degree of health and excitement. The faster it swings, the more excited and healthy it is. The slower it swings, the less healthy it is, although it is very excited.
Giorgio Veroteguela said, "In previous studies, zoologists have also found other emotions that can be reflected by the wagging of the dog's tail. If the dog is happy, its tail usually swings horizontally, and the width of the swing is very large. If the dog's tail is high and only the end of the tail swings, then the dog must be prepared to attack.
After obtaining these new research results, scientists are expected to successfully develop a magical puppy mood measuring instrument, which can accurately judge the dog's mood by measuring the wagging state of the dog's tail. The main component of the puppy mood measuring instrument is a sensor that can be tied to the dog's tail. The instrument can analyze the specific details of the dog's tail wagging in real time, including the speed, direction and arc of wagging, so as to judge the dog's mood. "
Dogs don't wag their tails when they see their owners.
In fact, what seems ordinary actually contains a lot of knowledge. I collected some relevant knowledge. Let's popularize the knowledge of dog tail together.
The bones of a dog's tail:
When you gently pinch the dog's tail, you can feel the bones inside. Although I don't want to put the dog tail and the sauce pig tail together, I have to say that the structure inside is very similar. There are some differences in the number of dog tails according to different breeds, but in general, it is about 20.
Why do dogs sometimes put their tails between their legs?
Dogs will put their tails between their legs when they are afraid or give up, because there are two glands on the left and right sides of the dog's anus, which will release 12 smells of their unique information. When they put their tails between their legs, they just want to emit their own smell as little as possible, which shows that they think their status is lower than that of other dogs or people, so they should restrain their own publicity.
I have a deep feeling about this: the stray dog I picked up has just arrived at my house for a month and has been holding its tail, but occasionally it wags its tail at me and will be held between Dangdang and even cats. Now he and Dangdang have become good friends and will never be dogs again.
Why do dogs wag their tails:
The book says that a dog's tail is similar to a human smile to show friendliness; But according to my observation, this usually refers to the dog's cheerful tail. Sometimes, before the dog attacks, the tail will flick slowly and stiffly, but in any case, it is an expression of emotion, but in most cases, it means happiness, especially when the owner comes to it. I heard that dogs don't wag their tails when no one is at home. If you have a video of a dog when no one is at home, share it with me. I really want to know if this is the case.
About the broken tail of a dog:
Some dogs need to cut off their tails in order to compete, which is a way to meet human aesthetic needs. When the dog was just a few days old, it was amputated from the first coccyx. It is said that the tail of the ancient English shepherd dog was first cut off because it showed that this kind of dog was a working shepherd dog and could be exempted from the corresponding tax, which was handed down from generation to generation.
Whatever the reason, I think this is very inhuman. My litter of puppies was amputated, and I felt ashamed, because at that time I was a novice breeder and didn't know how to respect dogs. In addition, if you want to cut off your tail, you must keep one or two of its coccygeal vertebrae. The amputation of Zigan's tail will affect the dog's balance.
Don't scratch the dog's tail;
This is not only out of respect for dogs, but also for safety reasons. I remember there was a news the year before last that a child was killed by a dog because the child had been pulling the dog's tail hard. After all, dogs are different from people. They just protect themselves in the most direct way. It is easier for animals to attack from behind than from the front. Imagine if someone stands behind you with a knife, is it more frightening than standing in front of you?
