Sheepherding is perhaps one of the oldest professions. But it's about to get some new tech to it. New heart monitoring collars will let sheep send a text to their shepherd whenever they are in danger. The concept was developed and proven in a recent experiment in Switzerland where dozen of sheep were fitted with heart monitoring collars and harassed by a pair of muzzled wolfdogs.
The stress of that got the sheeps' hearts pounding hard and it could be used as an alert system that texts a shepherd when his sheep are freaking out in any manner.
