Prey drive is no joke. My sister has a heeler/corgi mix, and taking her for a walk is an exercise in not dislocating your arm whenever she spots a small animal. She’s adorabloodthirsty.
Oddly her other dog, a heeler/pit mix, is super chill with no apparent prey drive whatsoever. I’m pretty sure you could hold a baby bird in front of his face and he’d just sniff at it dumbly with his tail wagging.
The power grid does have a major point of failure, in that vital components are on backorder for years out so most places don’t have the spare parts to get back up and running if widespread attacks on the grid occur.
