I agree with the posters who suggest a digging barrier, electric fence and other barrier options. I wouldn't put down a dog for killing a chicken, they didn't ask you to get chickens and tempt them, they don't know any better.
I agree that Ceasar Millan does have some great techniques, I've seen him stop dogs from killing bunnies.
