Swiss sheep to warn shepherds of wolf attacks by SMS
Using sheep to alert shepherds of an imminent wolf attack by text message is being tested in Switzerland where the predator appears to be back. The AFP reports.
In the trial, reported by the country's news agency ATS, around 10 sheep were each equipped with a heart monitor before being targeted by a pair of Wolfdogs -- both of which were muzzled.
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 repellant 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, Landry said, adding that it could also be used in tourist areas where guard dogs are not popular.
