Chaser was not only the smartest dog in the world, she was a beloved family member.
She was a witty, charming and sparkling dog who brought joy to everyone who met her.
She was not an obedient dog, she knew the obedience commands, but John Pilley only used those for safety. Obedience was not the goal of their relationship; their's was true teamwork.
Chaser, a purebred Border collie, was born on April 28, 2004, at Flint Hill Farms in Pauline, South Carolina. Eight weeks later, she became a member of the Pilley family, and John’s research partner in exploring the boundaries of the canine brain. She and John Pilley officially retired from public performances and film shoots in early 2018.
