Chaser is one smart Border Collie! In fact she’s been named “the world’s smartest dog” after her human, psychologist John W. Pilley, taught her to identify more than 1000 toys, each of which she can pick out of a pile.
Chaser can also uses the power of deduction to find toys she’s never seen before. Amazing! Here is Chaser showing off more of her remarkable memory skills on Nova Science a few years ago.
On July 30, 2019 Chaser passed away from natural causes at age 15. You can read more about her remarkable achievements and how her dad taught her here and listen to an interview of her family remembering her.
