The World's Smartest Dog - Chaser the Border Collie
Smartest Dog, Chaser the border collie
Chaser the border collie has the largest human vocabulary of any
dog, recognizing the names of more than 1,000 objects. Chaser leaps
ahead of the previous record holder, another border collie named
Rico, who knew 200 human words. The dog's vocabulary nearly puts her
on intellectual par with three-year-old human children.
Chaser's owner, John Pilley, has spent years training and testing
the limits of her intelligence. The 82-year-old psychology professor
used children's toys and other objects to teach Chaser nouns, and
she's still learning new things.
Over the course of three years, Pilley spent four to five hours a
day teaching Chaser about new objects and their names. Pilley jokes
that he almost had to go to bed at 8 p.m. just to keep up with the
Chaser's never-ending energy and attention to the training.
The Border Collie is a medium sized, energetic working dog. The body
is slightly longer than it is tall. The relatively flat skull is
moderate in width. The skull and muzzle are about the same length,
with a moderate stop. The strong teeth meet in a scissors bite. The
oval eyes are set well apart and brown in color, except in merles
where one or more eyes may be blue. The medium sized ears are set
well apart, either carried erect or simi erect. The front legs are
straight when viewed from the front but slightly sloping when viewed
from the side. The medium sized tail is set low reaching at least to
the hock, raising somewhat when the dog is excited. Dewclaws are
usually removed. The double coat is weather resistant, dense and
close-fitting. There are two coat varieties: a short, sleek coat
(about 1 inch long) and a coarse, rough coat (about 3 inches long).
The coat colors come in black and white, tri-color, red & white,
black & gray, yellow, yellow & white, sable, and all black. The
longer haired variety should have a mane and tail brush. The hair on
the face, ears and front legs is always short and sleek. Since
Border Collies are bred for working ability and intelligence rather
than for physical beauty, conformation varies widely.
