Chaser (dog)

Chaser (April 28, 2004 – July 23, 2019) was a Border Collie with the largest tested memory of any non-human animal. Chaser worked with behavioral psychologist John W. Pilley, at his home in Spartanburg, South Carolina, from eight weeks old in June 2004, until Pilley's death in June 2018. Pilley spent that time training her in a formal research project. Chaser could identify and retrieve 1,022 toys by name. Chaser had the largest tested memory of any non-human animal. In November 2021, Chaser was named the official mascot of Spartanburg Community College, the first mascot in the college's history.
