Not being born is only a problem if you had the notion that your potential life was cut off. A potential zygote, not an exiting zygote, obviously has no cognition by definition and by determinism. So there is no suffering. Nothing is being aborted. In any event, if this "dog x" has to exist, why not a healthier crossbreed?

I'm not proposing to cull the existing dogs, just not to further a breed and other breeds of dogs that suffer health problems due to our artificial breeding. There are lots of other dog breeds that do not suffer more health problems than average.
