There can be big dogs with an acceptable risk of HD. But it takes an effort most breeding organizations don't want to take and the breeding standard usually works against that anyway.
Hard to say what the most healthy "breed" is, in general, even for me who actually studied this stuff. Even crossbreeds will inherit the problems from their ancestors, crossbreeding isn't inherently better. For most people I recommend going for a dog that is around the size of a Beagle, but even Beagles are bred to have shorter legs than "wild type".
Also beware of breeds who reportedly have fewer issues... sometimes it's just that there haven't been published studies to that effect and often because the sample sizes are too small.
