“Surprisingly, studies have shown that married couples share more microorganisms with their dog than with each other!”

“Of all the animal species alive in the world now or in the past, only a relatively few have been domesticated by humans, most of them in just the last few thousand years of human history. The dog was the first, by a wide margin—the only animal believed to have been domesticated by itinerant human hunter-gatherers, long before the development of farming and permanent settlements.”

“And the olfactory part of a dog’s brain is forty times larger than a human’s; depending on the breed, a dog can have up to 300 million olfactory receptors in his nose, compared to about 6 million in ours. Even with that extreme superiority in equipment, dogs don’t merely smell a superstrong version of what we smell (or don’t smell); instead, they can perceive multiple layers of smell, which gives dogs a far greater range of information.”
