The new reigning smarty-pants pooch, Chaser, a border collie, possesses the largest human vocabulary of any dog! Chaser, who is a female dog - naturally - can recognize the names of more than 1,022 objects. According to a report by the New Scientist, Chaser can categorize the various objects based on function and shape as well as understand the basic concepts behind nouns and verbs! Impressive!
The last record holder, another border collie named Rico, knew 200 human words - still impressive, but Chaser's vocabulary is off the charts, putting her on intellectual par with three-year-old human children (and..um... some adult males we know ;).
As part of a three year training course at Wofford College, taught by psychologists Alliston Reid and John Pilley. Chaser was introduced to the names of 1,022 toys. Over the three years, Reid and Pilley taught the collie the names of 1022 toys by introducing them to her one by one, getting her to fetch the toy and then repeating the name to reinforce the association. They say there's no limit to what the dog can learn! Watch the video below and watch the amazing Chaser in action! (via Discovery News).
