If a dog has eyes that seem to tell you something or demand your attention, this could be the way of evolution to manipulate your feelings.
Researchers have found that dogs have developed muscles around their eyes that allow them to develop expressions that are particularly appealing to humans.
A small facial muscle allows dog eyes to mimic a "childish" expression that has a "nourishing reaction".
The study states that such "puppy eyes" have helped domesticated dogs connect with humans.
Previous studies have shown how such dog expressions can appeal to humans, but these studies from the UK and US have shown this. This was an anatomical change around the eyes of dogs to enable this.

This allows dogs to create what researchers call "expressive eyebrows" and "to create the illusion of human communication." [1
This muscle movement allows dogs to look "bigger, more childlike, and also resembles a movement that humans produce when they are sad."
She says that humans have an "unconscious predilection," dogs with one To protect and breed such an attractive trait that gives them an evolutionary advantage and strengthens them "Evidence is compelling that dogs have developed a muscle to lift the inner eyebrow after they have been domesticated by wolves," says Dr. Kaminski in a study that was published in the Proceedings of the National Academy of Sciences of London the US.
The results of British and American researchers in the field of anatomy and comparative psychology show that over millennia facial change has evolved from dogs living alongside humans.
Earlier research has shown that dogs use this term "puppy eyes" rather when a human being looks at them – suggesting that it is a deliberate behavior and intended for human consumption.
Anatomist and reporter co -The author, Professor Anne Burrows of Duquesne University in the USA, says that the changes in facial muscles of dogs were "remarkably fast" and "directly related to the improved social interaction of dogs with humans could be brought ".
Findings, according to Professor Bridget Waller of the University of Portsmouth, show "how important faces can be to attract our attention, and how powerful the facial expression can be in social interaction".
