First, the dog's IQ is not very high.
Many people may have the misconception that a pet dog has a high IQ. But in fact, even trained dogs can't understand us in daily life. Language. Dogs can do our corresponding actions mainly because they are trained or react next time. But we humans don't know what's going on in the dog's head, so we think he understands us, but we hope that's not the case at all. Among animals, the IQ of dogs is not even as high as that of pigs.
Second, dogs can do a lot of work after training.
Dogs can do a lot of work after training. In our daily life, we can see guide dogs, military dogs or daily pet dogs, and most of them are pet dogs. Dogs are trained to do simple housework, such as taking out the garbage or opening the door. But training takes a long time, because they don't know the meaning of their work without some emergency response. For example, take out the garbage. Actually, they don't understand why there is such a thing. They just take one object to another. It's a bit like throwing a frisbee.
Third, how to treat this news?
After this incident was reported, many people thought that they should train their own dogs with such dogs. But I still want to tell you here that it is actually very difficult for them to train pet dogs, because they need to learn and accept themselves constantly during the whole training process. For them, learning such things is not necessarily happy, so we don't need to let our pet dogs learn such things.
