Dog shows should be banned, as should the standardisation and classification systems related to pedigree breeds.
It encourages genetic engineering of the worse sort, where arbitrary aesthetic attributes are bred into and maintained in each particular breed, often with devastating results.
Another wonderful example of man's vanity expressed through eugenics and the deliberate manipulation of the genes, and hence the phenotype, of a helpless species of animal.
It could be argued, I suppose, that if such meddling leads to the increased well-being or longevity of a particular species, then it's acceptable. Such breeding techniques have been practiced for centuries to improve the productivity of the food industry and the efficiency and suitability of working animals - but the welfare of the animal has generally been of secondary importance to the returns - unless, of course, if neglecting this particular aspect has a negative effect on this productivity or efficiency.
But to continue to sculpt and fashion the gene pool of a species, when it's been proven that in a lot of breeds to do so does serious physiological damage to the animals concerned, is simply barbaric, unacceptable and intolerable.
