ATLANTA - We have all heard the old saying, "Dog is man's best friend" - but do dogs REALLY love their owners?

That's exactly what Emory University professor Gregory Berns set to find out in a recent study he did on a variety of dogs.

Professor Berns performed MRI's on the dogs - training them to hold still during the procedure.

What he found out was that a dog's brain works very similar to that of a human's brain. The MRI's revealed similar activity in the region of the brain called the caudate nucleus. Bottom line, the data suggests dogs love us and miss us when we're not around.
