The late psychologist, John Pilley, first began training Chaser in 2004. At the time, experts in the field were abuzz about another dog in Germany who’d been taught to tell apart 200 items. But Pilley, then 76, had a hunch Chaser might be capable of more. During her 15 years of life, Chaser displayed a remarkable knack for nouns, learning to distinguish between all the members of a massive collection of toys. But she didn’t just pick up words and remember them. She mastered them conceptually, distinguishing verbs from adjectives, and categorizing objects she’d never seen. Sadly, Chaser died in 2019. #chaserthedog #dogs #bordercollie #smartdog
