This news probably wouldn’t be that impressive if it was about a parrot, although I’ve never heard of one that knew the names of over 1,000 toys. And as smart as some people would like to think their dogs are, no one would expect a canine to know this much.
Chaser, a 6-year-old border collie, managed to learn the names of 1,022 different toys, which is more than any other animal has ever learned and around as much as a child around the age of three would be capable of learning.
Interested in how much of a vocabulary the dog would be able to develop, psychologists Allison Reid and John Pilley have worked intensively with Chaser for about three years. And their hard work certainly paid off, as they have proved that talking t your dog is not a waste of time.
