Dogs, reunited with their owners, cry tears of joy

Dogs literally cry tears of joy when they see their owners after they’ve been away, scientists have found in the first study of its kind that is also totally going to make us cry, too.

Published in the Current Biology journal, this study by Japanese researchers found not only that dogs shed happy tears, but also that the love hormone oxytocin — the same one that causes humans to feel emotional bonds with each other and with animals — may be underlying that mechanism.

Researcher and paper co-writer Takefumi Kikusui of Azabu University in Japan said in a press release about the study that he first began to wonder about oxytocin tears in dogs when his standard poodle gave birth to puppies about six years ago. He noticed then that his dog had tears in her eyes as she nursed the puppies, and has been fascinated by the topic ever since.

My parents bought my first dog for me when I was 5 years old. An Alaskan Husky, his name was Hank. And that’s about all I can put down on this page, right now.

    Scientists have decoded visual images from a dog’s brain, offering a first look at how the canine mind reconstructs what it sees.
    The results suggest that dogs are more attuned to actions in their environment rather than to who or what is doing the action. https://www.eurekalert.org/news-releases/964886
    The researchers recorded the fMRI neural data for two awake, unrestrained dogs as they watched videos in three 30-minute sessions, for a total of 90 minutes. They then used a machine-learning algorithm to analyze the patterns in the neural data.”
