Spot on. Breed a wee lurcher, which is pretty close to what, left alone, nature would design for a dog..., and then let it do what comes natural and chase a hare or a few rabbits and you're the epitome of cruelty to animals.
Yet it's totally acceptable to breed in mutations, remove natural attributes of the dog, and introduce a myriad of debilitating conditions and misery for the animal, and people are queuing up to buy that. The world's gone mad.
