Famously Smart

"My best metaphor is this is a 2-year-old toddler," Pilley told 60 Minutes. To which Cooper responds, “That’s how you think about your dog, a two-year-old toddler?” 

Just how smart is Chaser? He reportedly has a vocabulary more than twice that of a two-year-old child. A child that age usually has a vocabulary of 300 words. Chaser, at 10 years young, knows more than 1,000 English words. Chaser is owned by John Pilley, a retired psychology professor who has trained Chaser to recognize the names of 800 cloth toys, 116 balls and more than a hundred plastic toys. Chaser can pick out the toys when named by Pilley. And, yes, you'll see this in the demonstration on 60 Minutes below. Tell us, what do you think of this amazing Border Collie?
