9．Have you ever thought of why dogs are human's best friends？What's the bond（紧密关系） between human and dogs？A new study by Japanese scientist Miho Nagasawa seems to have found the answer，and it has to do with something named the cuddle（拥抱）chemical．
The cuddle chemical has another，more scientific name oxytocin（催产素）．Oxytocin is something in the blood that encourages bonding．Levels of oxytocin increase，for example，when a mother feeds her newborn baby．According to Nagasawa's study，levels of oxytocin can also go up when we look deeply into the eyes of a dog．
Humans and dogs have been working together for nearly 30，000years．In order to better understand how the cuddle chemical worked between dogs and humans，Nagasawa and his team did an experiment．They tested levels of oxytocin in dogs and humans，and then put them in a room to interact（交流）with each other．While in the room，the humans pet（抚摸）the dogs，spoke to the dogs，and looked into the dogs eyes．Then the scientists tested their levels of oxytocin again．
The researchers found that levels of oxytocin were higher in both humans and dogs after they interacted．However，levels were the highest in the humans and dogs that simply looked into each others eyes，without touch petting or talking．The longer the humans looked into the eyes of the dogs，the more cuddle chemical was let out．Nagasawa did the same experiment with humans and wolves（狼），but it did not give the same results．
