The others already mentioned the downed pasterns and what to do about that. I'd see a vet soon and get that treatment started...
But I wanted to add... while you're at the vet, it may be beneficial to get an x-ray of his hips. It's hard to tell from the videos and also because his front end is weak and his rear angulation is extreme (could just be how he moves to make up for all of it)... but he looks to be bunny hopping and swaying a bit in his rear end as he moves. His hips seem very weak and their movement is classic of HD. I would definitely get everything checked out back there.
As of the other, you can fix that with a good diet, correct exercise, and some supplements.
(although he's got some structure issues going on, he is beautiful. You can definitely tell he's well taken care of. He just needs some help in the bone/joint department)
