Her trainer, John Pilley, has posted videos of Chaser’s remarkable abilities on a You Tube Channel. In these clips from New Scientist, she responds to voice commands, correctly identifying both objects and actions.
Chaser’s vocabulary is the largest recorded for a canine. Over a period of three years she was taught one object at a time, with regular reviews, until she could correctly identify them. According to New Scientists, she never got less than 18 out of 20 right.
This smart dog’s accomplishments are, of course, only part of the story. They give us a glimpse into her ability to figure out what humans are trying to communicate. The other side of the equation remains a puzzle, with many pieces still missing.
