Your looking for guard hairs, primeness and size.
Guard hairs are the longer, course, strands of hair that protrude out beyond the animals softer underfur. They provide a protective barrier and usually get rub short or off, with a lot of denning.
Prime skins are hides that have a white appearance to them. Meaning the actual skin.
Rub your hand against the grain of the fur petting the animal backwards from tail to head. As you do this it will reveal the skins surface. Prime skins have a white appearance, non prime skins vary from blue to a tan.
