Dogs are a breed with relatively high IQ among animals. There are experiments that prove that dogs can clearly understand that humans and dogs are different. The way a dog plays with people is completely different from the way it plays with other dogs. In addition to accurately identifying different types of dogs, dogs can also distinguish the difference between dog faces and other species, such as humans, cats, rats, sheep, cows, birds and reptiles. Even whether the face on the screen is a front or side face, the dog can accurately select the side of the dog's face.
Dogs’ hearing and smell are very sensitive, so they mainly identify their owners based on their smell and voice. In addition, they can also judge their owners through vision. Although dogs are not as good at color recognition as humans, they can remember the general outline of their owners and thus recognize that their owners are not the same kind.
In addition, dogs’ perceptions are very keen. They sense human emotions not by looking, but by truly “feeling” them. They can hear small differences in sounds and heartbeats. When a person is in a negative emotional state, the heartbeat will be unstable and the breath will be faster. Dogs may sense our emotional changes through these details.
