Video: Smartest Dog Ever Can Pick Out 1,022 Toys By Name | Popular Science
by Scott Smith
A border collie named Chaser has learned the names of 1,022 individual items — more than any other animal, even the legendary Alex the parrot.
Psychologists Alliston Reid and John Pilley of Wofford College in Spartanburg, S.C., wanted to test if there was a limit to the amount of words a border collie could learn, so they taught Chaser the names of 1,022 toys, one by one, for three years. New Scientist reports that they got her to fetch the toy and then they repeated the name to reinforce her understanding.
