The thing is though it isn't just that he had the rock disease and the rokakaka cured him of it, he has been shown on multiple occasions shifting between dog form and rock form. In other words he shows the exact same physiology as a rock human. He can camouflage, he can become a rock whenever he wants and whatnot.

So there is no real distinction or difference between Iwasuke and the Rock humans besides that Iwasuke is a dog.
