How much thought goes on behind those eyes? A lot, in this case. Six-year-old "Betsy" can put names to objects faster than a great ape, and her vocabulary is at 340 words and counting. Her smarts showed up early: At ten weeks she would sit on command and was soon picking up on names of items and rushing to retrieve them—ball, rope, paper, box, keys, and dozens more. She now knows at least 15 people by name, and in scientific tests she's proved skilled at linking photographs with the objects they represent. Says her owner, "She's a dog in a human [pack]. We're learning her language, and she's learning ours."
