Have you ever given it a thought that how your dogs who have become a part of your family understand your voice? All of it is done with the help of their different parts of the brain which they use for processing the negative and positive human emotions. According to a study, living in close contact with the humans, the dogs have been able to establish special skills like recognising the emotional cues which they hear in the human voice, body odour and posture too. The dogs also start recognising and reading different facial expressions which help them in interacting and communicating proficiently with the human beings. The study also showed that the dogs turn their heads towards left when they feel the expression of anger, fear or happiness on the faces of the humans. Opposite happened when the humans expressed the emotions of surprise. The reason for this behaviour in the dogs is that they feel such expressions as relaxed and not threatening. A scientist from a reputed university said,

"Clearly arousing, negative emotions seem to be processed by the right hemisphere of a dog's brain, and more positive emotions by the left side."
During a research, the dogs were shown a picture of a man and a woman to 26 dogs who were eating. The photos were deliberately arranged to the sights of the animals’ sight of line. The photos were showing six different and basic human emotions like anger, fear, happiness, sadness, surprise, and disgust and being neutral. The team of the researchers discovered that the dogs responded greater and the cardiac functionality was also better when they were shown photographs which expressed emotions like anger, fear and happiness. They also took longer time to resume eating after they saw these pictures. The heartbeat of the dogs increased which meant that they experienced high level of stress when they saw these pictures. The end result of the study gave full support to the lopsided emotional cadence o the brains of the dogs for processing basic emotions of the human beings.
