That's pretty unique. I'd guess the dog doesn't mind at all. Just think of the attention it got while being braided.
Right now, my LGD is in mid-shed. She's got such a heavy coat, I can't even brush her, it's more like thatching. Does she mind me picking her undercoat out by the handful? Hell, no! She loves the attention and the hands-on interaction.
Dogs are wonderfully forgiving souls.
