This reaction during the reunion of a dog and its owner is probably linked to the Oocin hormone, according to the researchers. "Oxytocin is aHormone produced In the hypothalamus and released into the blood circulation by the pituitary gland, "explains Harvard Health, noting that it is generally produced at higher levels during childbirth or demonstrations of affection - that is why it is often called "Love drugs" or "love" hormone. "

Kikusui said his research started six years ago after noticing tears in the eyes of one of his poodles who had just given birth and breastfeeding the puppies. "It gave me the idea that oxytocin could increase tears," he said. According to the researcher, a dog's tears do not fall as they often do when humans cry, but you can always see unmistakable tears in the eyes of a dog. As part of the study, he and his researchers found that the volume of tear of dogs also increased when they added oxytocin to their eyes - supporting the idea that the liberation of oxytocin plays a role in Tears produced by dogs when they find their owner.

"We have found that dogs shed tears associated with positive emotions. We have also discovered oxytocin as a possible underlying mechanism," confirmed Kikusui.
