The patella's is the back Knees and I don't see how a harness could hurt those. The trachea has to do with breathing so I would think that is most important to be careful about. I would never ever hook a leash to the collar it's just to risky. If for some reason they get luxating patella's from a harness which I think would be hard there is a surgery to fix that with collapsing trachea the surgery is still experimental and doesn't always work. Jumping would be worse for the patella's then a harness.
