This study got fancy. Japanese scientists found out that both dogs and people who gazed into each other's eyes developed elevated levels of a hormone-like chemical called Oxytocin. Sometimes referred to as the "Cuddle Hormone," Oxytocin creates a wide range of positive effects that lead to bonding, attachment, and it plays a significant role between mothers and babies.
The study demonstrates that dogs and humans have a special - maybe even unique - relationship. When we spend time with dogs and stare into their eyes as they stare into ours, good stuff happens to our brains and to dogs' brains as well.
Here are links to information about the study:
All pets are valuable. But dogs provide something extra to celebrate. Dogs are good for us, and we are good for them.
Now go give your dog a pet, look into her eyes, and watch how she looks back at you. Aside from dogs and people, no other animals on the planet will ever look at you that way.
