Dogs cry when reunited with their owners after a period of absence

Tears of joy. Even dogs "cry" from emotions, when reunited with their owners after a long period of absence, according to a study from the Chinese university of "Azabu" as well as the medical one "Jichi", writes Vanityfair.

The team studied the behavior of 22 dogs and examined their reactions. The researchers placed strips of paper under the dogs' eyes during normal interaction with their owners for a minute before "hugging" them after months or even five to seven hours without each other.

The study found that when the animals saw their owners, and only then, their tear production increased. They did not "cry" when they saw people they knew and who were not their owners.

The researchers tried to figure out if it was an emotional reaction. To do this, they applied a solution to dogs containing oxytocin, a hormone that plays an important role in emotional bonding, and found that, after using the hormone, the dogs' tears increased dramatically.

Tears are known to help dogs keep their tear ducts clear, but so far no studies have linked them to emotional response.

"We had never heard of animals shedding tears in happy situations when meeting their owners," said Takefumi Kikusui, one of the authors of the study, published in the journal Current Biology.

On the other hand, the dog's eye contact and moving eyes have a powerful effect on the owner: they stimulate the secretion of oxytocin, which makes him more loving or protective of his four-legged friend (as happens with children).

"Tears can play an important role in deepening mutual relationships and further strengthening the bond between species," the study authors write.
