GW, I don't think it's so much about whether it would work. I think it's more about who's going to create the program, pay for it, administer it, and do the actual leg work. The Devil is in the details, as they say.
Maybe coyotes are a bad example. They're just too smart and adaptable, and I think it's impossible to stop their range expansion. Long term, they adapt to any deterrent, and nothing can completely stop them. I guess a great pyranese or similar dog is the most humane solution. The choice boils down to feeding 1 huge dog, or a bunch of little dogs.
