Meanwhile in Switzerland: sheep to warn shepherds of wolf attacks by SMS:

During the experiment, the change in the flock’s heartbeat was found to be significant enough to imagine a system whereby the sheep could be fitted with a collar that releases a repellent to drive the wolf away, while also sending an SMS to the shepherd. The device is aimed at owners of small flocks who lack the funds to keep a sheepdog

Why do I blog this? This is an intriguing example of tech/animal interaction that seem to be more and more common these days. What would the unintended consequences (on the part of the sheep, the wolf and the sheperd)?
