Humans and dogs have evolved alongside each other for 15,000 years, and there are now some 80 million dogs in the U.S. — more dogs than children — but as CNN's Anderson Cooper learned on assignment for 60 Minutes, we still know very little about their brains.
“We all think we know everything about dogs, but they're actually one of the least studied of the animals out there,” says Cooper.
In his latest 60 Minutes story, Cooper and producer Denise Cetta reported on the latest scientific research on dog intelligence, but for Cooper, learning about the minds of dogs was more than just an assignment.
“I'm a total dog person,” says Cooper. “I just really love dogs. I like other people's dogs. I like dogs of all kinds. Pit bulls– I actually love pit bulls.”
