I always recommend OFA pre-lims done on puppies right at your pup's age - even if no symptoms or signs are present. X-rays done now will give you far more options, and preventative strategies than ignoring it.
Bunny hopping is a telltale sign of hip dysplasia and should never be ignored in my view. It is not a normal gait for a puppy, even if panosteitis is the only condition. There can be many causes of it, and some easily correctable with rest and range of motion exercises, but you want to identify early for the most options, especially if it turns out to be dysplasia.
Get your pup on several joint supplements critical for big dogs now as well - glucosamine and chondroitin (Synflex is a great product and easily assimilated), celadrin or hyaluronic acid for joint lubrication, and potentially wobenzym if necessary.
Good luck!
