I dunno, I've eaten dog before (tends to taste a bit like what it was eating, coconut and scraps, yech). I also had a dog that got hit by a car and the neighbors got to it before we did. Apparently they ate well that night. Shit happens. Things are born, die, sometimes get eaten by other things. That said I could never eat my own dog (extreme starvation situation excepted). Your emotional attachment is just that, an emotional attachment and personally I'm fine with offending your sensibilities if it yields a cure for some nasty disease.
All that said however, I'm a firm believer that *all* animals should be treated with compassion and respect. I consider brutal treatment of cows destined for a grease burger just as despicable as torturing lab monkeys with toxic cosmetics. Why single out dogs for special treatment?
