- Dogs often bounce around uncontrollably when their favorite humans come home from work.
- Now a new study reveals many also cry happy “tears of joy” just like people!
- When Professor Takefumi Kikusui’s poodle had puppies six years ago, he noticed the dog’s face change when it nursed the puppies. His furry friend had tears in her eyes.
- “That gave me the idea that oxytocin might increase tears,” Kikusui says in a media release.
