I read a news story awhile ago, about a guy who got sick of hearing his neighbour's dog's incessant barking (apparently, it was left outside quite often); he took the dog into a vet, had it debarked, and returned it to the neighbour's yard!
I'm a huge fan of critters, and I totally feel his pain...but I would never even think of doing such a thing. My neighbours have a nuisance barker. I've actually contemplated buying a dog whistle to blow, to try and curb it. I have also contemplated walking over there, and feeding it a big spoonful of peanut butter.
If I were to debark anything, it would be my neighbour's rambunctious, rude, noisy children. I don't think either of them possess an "indoor voice."
