Chaser was a Border Collie that is often called the “smartest dog in the world”. She is said to have known over 1,000 different words!
Chaser enjoyed the attention of scientists, led by her owner and trainer, retired psychology professor John Pilley. Chaser responded correctly to identifying a noun as an object 95% of the time. Not only was Chaser able to pick out the correct toy out of over 1,000 every time, she was able to identify toys she's never seen by process of elimination - all based on verbal commands. source: questionsondogsandcats.blogspot.com/2011/09/who-has-smartest-dog.html
