He is holding up that one foot in the video.
I don't in know in puppies, to be honest. Kabota has one leg a little smaller than the other, and he sits "sloppy" and he bunny hopped all the time before we built up the muscle in his back end and forced him to use the lame leg. Now he never does it. And the sitting like that, I've seen dogs do that who don't have any hip problems at all.
I would visit another vet for a second opinion. Keep in mind, HD is not a death sentence in this day and age. There are things you can do. I work with a guy who has a GSD with severe HD. He had surgery done on her and now you can't tell her from his other GSD. They both run and jump and act like the crazy young GSDs they are.
