Dog People, Cat People: What Does Science Tell Us About Pets?

Posted: Updated:

Since they were first domesticated between 15,000 and 30,000 years ago, dogs have been man's best friend. Pets provide us with so much more than entertainment or companionship. In fact, there's a whole field of scientific inquiry called anthrozoology, which purports to investigate the relationships between humans and non-human animals.

Is there any truth to the idea that cat people and dog people are fundamentally different? Can having a dog improve your chances of getting a date? And do people really look like their pets? What does the science say?

To learn more about our relationships with our four-legged friends from an evidence-based perspective, I reached out to Dr. Hal Herzog, anthrozoologist and author of "Some We Love, Some We Hate, Some We Eat: Why It's So Hard To Think Straight About Animals."
