"World's Smartest" dog featured on "60 Minutes"

"60 Minutes" introduced America to "The World's Smartest Dog" Sunday night -- and she lives in South Carolina.

Chaser, a border collie whose owner is a former Wofford College professor, recognizes more than 1,000 words. To put that number into perspective, most human 2-year-olds know about 300 words.

The work Chaser's owner, professor John Pilley, has done is giving scientists insight into the minds of dogs.
