It turns out that dogs are born with “ ability to understand human instructions '' by nature
Many people have seen dogs perform tricks such as “wait” and “hand”. I don't know if this "dog's ability to understand human instructions" is innate, or whether it was acquired by living with humans since puppies. Meanwhile, experiments with stray dogs that have never lived with humans have revealed that dogs are more likely to understand human instructions by nature.

Stray dogs have the natural ability to understand human gestures
It is estimated that there are 300 million stray dogs on the earth, of which about one-tenth, or about 30 million, live in India. It is said that 20,000 people die every year in India due to such stray dog-borne rabies. For this reason, stray dogs have become a social issue in India.
Therefore, a research group of ethnologist Anidinta Badra and others who work for the Indian Academy of Science Education conducted an experiment to see if 160 stray dogs can understand human gestures to deepen their understanding of the ecology of stray dogs. . The research group first explored stray dogs in three cities in West Bengal, India. The stray dogs were placed in opaque bowls and given to the stray dogs, so that even stray dogs who were not accustomed to receiving food from humans could conduct experiments. At this point, 37 stray dogs that were unable to approach humans, even when given chicken, were excluded from the study.
Next, the research group prepared a “ bowl with a piece of chicken '' and an “ empty bowl with only the smell of chicken '' in a place that the dog and the person in charge of the experiment did not see, and closed it with cardboard cardboard And handed it to the person in charge. Not only dogs but also the experimenter did not know the bowl with chicken, so that the psychology of the staff did not affect the experimental resultsDouble blindIt is to maintain the state of.
The experimenter makes a gesture of randomly pointing one of the bowls on the ground.
Then, three experiments were performed per animal to check whether the dog approached the bowl and whether the bowl the dog approached was a bowl pointed to by a human.
As a result, almost half of the stray dogs were unable to approach either bowl. “ Because of the dangers of rabies and hygiene issues, stray dogs in India can be beaten away and fed with poisoned food, so he can approach with caution, '' said Badra. It wasn't. "
On the other hand, the proportion of stray dogs approaching the bowl approaching the “bowl pointed by humans” was a significant 80%. Also, if a stray dog was able to eat chicken in the first experiment, the probability that the stray dog approached the "bowl pointed to by a human" in the second and subsequent experiments was higher.
"This experiment shows that stray dogs have a very good ability to understand body language, which means that they can carefully observe humans in the first meeting and understand their instructions well. It shows that you are born. "
