A study inspired by a scientist’s dog found that dogs cried happily when their owners came home, as Professor Takefumi Kikusui noticed that his dog was crying, and Professor Takefumi said: “It gave me the idea that oxytocin might increase tears.”
Professor Takefumi, of Azabu University in Japan, was inspired by this observation and went on to discover that dogs had more tears in their eyes than usual when reunited with their owners..
The researchers noted that dogs’ tears are caused by an increase in oxytocin, the “love hormone”, which evokes feelings of love and affection in dogs when they see their owners and fill their eyes with tears.
Professor Takefumi said: “We have never heard of the discovery that animals shed tears in joyful situations, such as being reunited with their owners.”
The study, which was published in the journalCurrent Biology Dogs shed tears in happy situations, but the researchers haven’t tested what happens with negative emotions, and they haven’t yet discovered whether dogs experience the same emotional reaction to their fellow canine friends, but they hope to do so soon.
