I think there are many links but a lot of factors involved. For example, used to do SchH with some Rottweilers and a few of these dogs literally could not breathe after 15 barks. They were strong dogs, good barking and aggression, nice muscle, but...maybe their heavy bone structure and huge chests just make it more work? I mean, essentially they are performing the same things as a lighter dog like a 45lb Mal or 65lb GSD. It seems like it has to take more effort for a bigger, wider, heavier dog to perform the exact same tasks? As long as the dog has the physical mass necessary to do a task, more bulk probably doesn't help (otherwise why are gymnasts typically under 5'2"? talk about agility). And that's not even considering the skeletal anatomy and how angulation comes into play....
