More than fifty years ago, Jane Goodall made a discovery that shook some scientists — particularly those that had long lists of all the things that made humans unique and superior to nonhumans. She saw Chimpanzees using tools.
Since then, other researchers have found other nonhumans using tools, from dolphins who use sponges to protect their beaks to elephants using tools to scratch itches, reach food, and plug water holes. Even crows use tools. But, as far as I know, no researchers have studied whether dogs use tools.
I’d argue that Koala, a guide dog educated at Guiding Eyes for the Blind in Yorktown Heights, New York, uses tools.
Koala had a problem. When she tried to chew on her antler, it would move. Sometimes it would slip out of her paws — oh, if only she had thumbs — and skitter across the floor. She loved the noise it made (especially when Deni was on the phone), but it was not efficient. She wanted to chew.
