If you want to learn scientific research on keeping pets well, you must master some physiological knowledge of dogs. Do you know all the following aspects? Of course, there is no need to talk about the extraordinary English listening and smell. The position of military dogs is an identification with their extraordinary smell.

The sense of smell itself has long been very agile, but they also have strong English listening skills that are four times more capable than people. Not only can you hear subtle sounds in the distance, they also have an accurate sense of direction for the sound. Even if the dog sleeps at night, his ears are still busy working, carefully monitoring the sounds around him. It is the instinctive reaction of the dog's house guarding the hospital.

The dog can also hear the owner's mentality from the sound, so the dog does not need to be punished for making mistakes. The tone of anger is enough to let it understand its incorrectness.

Eye vision

The Creator is fair, giving the dog a strong sense of smell and hearing system, and returning the dog's red and green blind and myopic eyes!

The dog's eyes do not have the ability to distinguish tones, and its cognitive ability of color is the concentration value of black and white graphics, so the dog can see the items clearly at night.

Although eyes have poor vision, like people, the eyes are windows of the soul. They like to use their eyes to express their emotions. People can understand this kind of emotions expressed by gaze.

Dream and yawn

Like humans, dogs yawn when they are bored and yawn when they are anxious. Therefore, it is not that dogs yawn during training that they are bored with training, they are just more anxious.
