1. Dogs can sense weather changes
Animals are very sensitive, and they can see the slightest disturbance. Therefore, excluding strangers approaching, if the dog suddenly fidgets, barks, etc., it is probably because the weather has changed, maybe a storm is coming, Maybe the smog is coming.
2. Dogs will “watch words”
The training behavior of humans for dogs is not actually that dogs can “understand” human language, but that they can “observe words and colors”, complete certain actions according to some behavioral instructions, and then keep them in mind.
3. A dog’s nose is moist to keep the sense of smell sharp
Dogs like to lick their noses, so their noses are often wet. This actually means that dogs are healthy and their noses are wet, so they can come into contact with more odor molecules and better distinguish between different odors.
4. Dogs have poor ability to distinguish colors
There are only three colors of yellow, blue and gray in the dog’s world, so in their eyes, there is no extra color, which leads to the poor ability of the dog to distinguish colors.
5. The dog’s body heat dissipation is poor
The fur on the dog is thick and abundant. Even if there are sweat glands on the body, the perspiration ability is poor, and it cannot dissipate heat in time. Therefore, in the hot summer, the dog will pant heavily, secrete saliva through the tongue, and evaporate to dissipate heat. So as to achieve the purpose of heat dissipation.
