I don't think it's possible to have a BREED that shouldn't be bred. There's a huge spectrum of dogs classified in a 'breed.'
There's the Working bred dogs, which serve a purpose and are bred for their ability to work, and show bred dogs-- which are bred for their looks and performance in show. I think both of these are (or should be) bred with health in mind.
On the other end, there's Puppy mills and back yard breeders. These dogs are normally bred without health, temperament and genetic sound-ness at all. As a result, you get screwed-up pups. I don't think These Dogs should be bred. Of any breed.
Somewhere in between, you have people breeding different types of lines, like the bulldogs earlier in the thread. That's hardly the same breed.
Like it was said above, you can't classify a breed as one type anymore, so you can't really say a breed shouldn't or should be bred, I guess.
