d friend scratching at your feet. When you look down, those cute eyes are almost impossible to resist.

What is it about a dog&39;s gaze that makes it so charming？ A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.

The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.

The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.

Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.

Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.

This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.
