In the context of "why get a dog that is a known barker if you can't/won't tolerate it, or if you live where barking is a nuisance", I agree. I don't really care if it's the norm among breeders. If you live in a town house, don't pick a dog that is a KNOWN barker. Duh.
HOWEVER, sometimes circumstances change, dogs change, or problems arise where dealing with a nuisance barker suddenly becomes an issue. Or not necessarily suddenly, but where it wasn't a problem before it is now. The options are training, 100% supervision, a citronella collar, a bark collar, debarking, rehoming, and euthanasia. When owners find themselves in a situation where barking becomes a deal breaker, debarking is a very realistic and humane option compared to some of the other choices. Especially with the economy such as it is where homeless dogs are at an all time high making the option to rehome, especially a dog with a known vice (the barking), next to impossible.
So that leaves humane euthanasia, or bark collars. Citronella collars are a great option if they work, but many dogs figure out quickly that they can bark, bark, bark, BARK and empty the can really quick, and then carry on barking without any repercussions. It took my jack russell (who, by the way, is not debarked) all of 10 minutes to figure that out. And electronic bark collars are, in my opinion, much worse than a one time procedure, and far more risky. They carry the possibility of shorting out or malfunctioning (most come equipped with a safety option where they shut off after so many barks and reset so they don't hurt the dog). My recommendation would be to never leave it on the dog unsupervised, which pretty much negates the point of using it on a nuisance barker. And, they cause sensations (I wouldn't say painful, because I've tried them and they don't hurt, per se, but when compared to debarking it is a sensation every time as a correction, versus no sensation) everytime they go off. So when weighed against a one time, day-surgery with a short recovery, or depending on an electronic bark collar for the the rest of the dogs life, I'd absolutely suggest debarking.
Plus, bark collars are known to contribute to behavioral issues because they prohibit the dog from barking at all, where as debarking does not. Barking is a form of communication and is essential for maintaining a healthy temperament.
Over all, if a person finds themselves with a dog that is a nuisance barker, I don't think they should rule out debarking as a humane alternative. But, I DON'T think debarking should be an option simply so people can get breeds that are not well suited to their living conditions. Does that make sense?
