Dogs have been our loyal companions for tens of thousands of years, but their role extends far beyond simple pets.
Scientific research is uncovering fascinating evidence that the bond between humans and dogs is unlike any other interspecies relationship.
From increasing our life expectancy to being hardwired to communicate with us, dogs truly are man’s best friend—and science has the proof!
Oxytocin: The Cuddle Hormone That Bonds Us
When you share a gaze with your furry best friend or they playfully lick your face, you’re actually experiencing a surge of oxytocin—the powerful “cuddle hormone” that cultivates bonding, trust, and connection between two beings.
Studies show that oxytocin rises in both a dog and their owner during positive interactions. This facilitates enhanced communication, empathy, and the forging of that beautiful loyalty between human and pup that makes the bond so unique.
Dogs Understand Our Body Language & Gestures
Impressively, dogs have developed specialized skills for understanding human gestures and movements in ways no other species can match. From following the pointing of our fingers to reading our facial expressions and eye movements, pups are skilled at basic human communication.
Research suggests their brains may have evolved to seamlessly integrate these types of human cues. No wonder they seem to just “get” us like no other pet!
We Both Experience Healthy Hormonal Benefits
Science shows that simply petting a dog can help regulate our stress hormones like cortisol, providing us with ample health benefits in the process. But did you know the feeling is mutual?
Studies reveal that dogs’ oxytocin levels spike during friendly interactions with their humans—mirroring the same calming effects we experience ourselves! Talk about a mutually beneficial relationship.
Their Loyalty & Companionship Is Life-Lengthening
Having a canine companion not only keeps us active and provides emotional support, it can also lead to a longer life expectancy. Research on the health benefits of dog ownership found that seniors who owned dogs were better able to cope with stressful situations and had fewer health issues—including a decreased risk of heart disease.
Dogs really can have a powerful, healthful impact on both our mental and physical wellness in ways science is only just beginning to understand.
Dogs May Have Been Domesticated Longer Than We Thought
While most research suggests that dogs were first domesticated from wolves between 18,000 to 30,000 years ago, some surprising new evidence points to the possibility that ancestral dogs may have emerged as far back as 40,000 years ago.
The jury is still out, but if that proves to be the case, it would mean dogs have been our loyal companions for much longer than previously believed, making their status as “man’s best friend” all the more meaningful.
So the next time your furry best friend greets you with that irresistible wagging tail and unconditional love, remember—there’s some serious science behind your special bond that’s uniquely human. From increasing oxytocin to boosting your health, dogs really are hardwired to be our lifelong companions.
