As a cyclist I’ve had occasion to leap sideways when a mutt barks suddenly, even when its behind a gate. It puzzled me why some dogs started barking when they couldn’t possibly hear or see me, so on behalf of the magazine, Cycling World, I spent the best part of six months researching the topic, doing experiments and persuading canine psychologists to talk to me. The resulting article came out in Cycling World in 2004. This month I updated the piece and it is published online for the first time in Kalkion at: http://kalkion.com/column/971/why-dogs-bark
