Really? I think the British and American fancies have done a great job with the breed; the dogs have lovely personalities and are very healthy on average with great care being taken to health-test dogs to prevent proliferation of the issues they are prone to. They are dwarfed because a dwarfed dog of their type was considered functionally useful for herding [everything but sheep], driving, ratting, guarding, and hunting in the mountains of Wales for the last 3000 years or so; not because someone thought it was cute and inbred a bunch of dogs to look that way.
She's got a lot to say about 'the victims of human breeding programs for purebred dogs', too (pertaining especially to the sensationalist, anti-purebred special Pedigree Dogs Exposed which got so many people excited). Most of which I strongly agree with.
