Addendum!
Here are the sources of the current batch of fiber I'm turning into yarn: Ajo and Vuelker. Both are German Shepherds. Ajo is younger and lighter, source of both washed and unwashed fiber, and Vueller is older, darker one, source of the darker "batt" that is next to be spun.
Their photos and fur are thanks to @jnye, coming from the wilds of northern Michigan. Those long dark guard hairs do a great job of covering up the lighter undercoat hidden below!
@maru Note the availability of clean water for splashing in! This might help explain the lack of doggy smell to the fur that you asked about. 😂
