Dogs can judge whether the owner's life is in danger through the owner's emotions, smell, movements, tone, etc. Because fear or anger are strong signals sent by the body, many people lie to dogs. He fainted, but the dog didn't care about him, so he thought the dog was disloyal, which was actually wrong. If a dog has a relatively high IQ and is loyal and loving to its owner, it will be more worried about its owner, such as a golden retriever. Some dog breeds with free personalities and low obedience may sense that their owners are acting and do not want to cooperate, such as the famous three sledding fools, Huskies, Samoyeds and Alaskans.
