Some dogs just don't like it, they aren't people and don't hug each other I think it just freaks some dogs out. Eko doesn't like it, he used to as a puppy but now he would much rather lay next to me or at my feet and be petted. My other dog loves cuddles, even lets me hold her on her back like a baby lol so I just give all of the cuddles to her.
And all of the noisemaking, assuming he's not in pain or anything he might just be being a drama queen. Eko is the same way he will yelp like he's being murdered if he is even slightly uncomfortable. My vet says she knows a lot of GSDs like that.
