From George W. Bush, Decision Points. Chapter “Freedom Agenda,” p. 433:

Putin and I both loved physical fitness. Vladimir worked out hard, swam regularly, and practiced judo. We were both competitive people. On his visit to Camp David, I introduced Putin to our Scottish terrier, Barney. He wasn’t very impressed. On my next trip to Russia, Vladimir asked if I wanted to meet his dog, Koni. Sure, I said. As we walked along the birch-lined grounds of his dacha, a big black Labrador came charging across the lawn. With a twinkle in his eye, Vladimir said, “Bigger, stronger, and faster than Barney.” I later told the story to my friend, Prime Minister Stephen Harper of Canada. “You’re lucky he only showed you his dog.”
