Matt Roush says...
Are our conversations with man’s (and woman’s) best friend one-sided, or are dogs actually capable of talking back? In a fascinating installment titled “Can Dogs Talk?”, Nova explores the science of canine cognition in the largest animal communication study ever conducted. The catalyst: so-called “button dogs” who press buttons emitting sounds that approximate human speech. Are they actually expressing what they’re thinking, or are they just following their training? Scientists draw conclusions from millions of button presses involving thousands of dogs. If only Lassie had known about this every time little Timmy fell in the well!
