A Japanese scientist has shown that dogs "cry" and shed "happy tears" when their owners return home.
MirrorOnline reports the new study, published in journal Current Biology, has discovered has proven what every dog-lover will no doubt have hoped - and that our dogs are delighted when we come home to them. The research took place at Azabu University in Japan after scientist Professor Takefumi Kikusui noticed his pet appeared to tear up when she nursed her puppies.
Professor Kikusui explained that canines produce tears, but they don't fall like humans' do - so he was investigated how their emotions interact with the physical suggestion of tears. He said: "That gave me the idea that oxytocin might increase tears."
