On the eve of Crufts, the most famous dog show in the world, geneticist
Malcolm Willis argues that the British are dangerously indifferent to the fundamental health of their dogs' bodies. We may be a nation of dog lovers but too often, he maintains, we have allowed fashion rather than health to dictate the way we breed our dogs.
He contrasts the British approach to that of Sweden where a measure of control is in the process of eliminating some of the hereditary defects which plague British breeds. Director IAN SUTHERLAND
