People invent all sorts of weird crap all the time. Did we mention the burger-shaped USB hand-warmer recently? But this weird crap is also slightly sadistic. It's an electric-shock collar for dogs.
When GPS experts hook up with the makers of electric collars it makes me think about gps-controlled electronic tagging: you know - when there are electric shock penalties to straying beyond a certain area. Sort of "Battleship Royale" style. I've heard this idea mooted before as an extension of the current tagging of prisoners system.
In the basic concept, straying beyond the allowed parameters wouldn't just alert the police to your transgression - it could also give you an electric shock, or a pacifying injection. Pretty nasty.
Obviously we're not there yet, thank god, so back to the dog collars: I'm no expert in dog behaviour, but if you electrocute the poor thing through the collar, surely it means the pooch is going to really hate the collar, and quite probably you.
Of course you need to discipline pets, but maybe not like this.
