Whoa! Slow down! From your post, you have a normal puppy with no issues. LOTS of puppies bunny hop, and lots of puppies do the lazy frog sit, even older dogs with perfectly normal hips. Even my old guy, now five years old bunny hoped at time until he was two. He OFA'd Good: Bunny hopping was just him kicking up his heels and having fun outside!
Take a big breath, relax, and let your pup be a pup, ackward, lazy at times, crazy at times, athletic sometimes, uncoordinated and silly sometimes. None of it indicates Hip Displasia.
I don't know enough about Penn-Hip to comment on that, but I would suggest x-rays when she is under for spaying, just for your own peace of mind. And lots of dogs with mild displasia go on to live full, active, pain-free lives with proper management and supplements.
Just relax, I'm sure your pup is fine.
