The hit CBS news magazine 60 Minutes ran what was no doubt one of its most popular segments of recent years, “The Smartest Dog in the World,” featuring Chaser, the border collie who learned more than 1,000 words and names.
As shown in the segment, Chaser accomplished that incredible feat because her owner, retired psychology professor John Pilley, spent five hours a day, five days a week training the white-and-black spotted pooch to associate certain words with objects such as toys.
As a result, Chaser ended up with a vocabulary three times greater than that of the average toddler. It’s impressive, to be sure, especially since very little was known about the power of the canine brain until quite recently, as correspondent Anderson Cooper pointed out at the top of the piece.
