The dog community has lost someone special this week. Chaser, the Border Collie who knew over 1000 words, has died at the age of 15. She outlived the man who trained her, John Pilley, who was a Professor Emeritus in Psychology at Wofford College. Pilley began training her at age 75 after receiving the dog as a gift from his wife Sally, and passed away a year ago at the age of 89. Pilley’s training of Chaser revealed that dogs’ language abilities are so much more extensive than previously realized.
