Sheep in Switzerland could soon be able to raise the alert via text message when attacked by wolves.
The system works by placing a collar on the sheep that can monitor its heart rate, when the sheep becomes too distressed the heart rate increases and the device automatically sends a text message to call for help.
The system has been developed following an increasing number of attacks on sheep by wolves in Switzerland and could be rolled out in other countries as well if it is deemed a success.
"Swiss sheep could soon be texting shepherds for help when they are being stalked or attacked by wolves."
