My staffie has some of these marks; strange de-pigmented areas that sometimes are the precursor to some infection or other, but sometimes they go away without "blowing up". I wondered for the longest time if she got them from daily living, out and about in the woods, chewing stuff, etc., because some of the permanent spots are where her canine teeth lay against her lower lip, and things like that. But other spots, especially on the upper muzzle/nose, there's hair loss in addition to the loss of pigmentation, which is a good indication for me that something nasty is coming. She's had serious infections
before, so whenever these spots show up now I repress my urge to freak out, and dob them with some chelated silver
a couple of times a day for a few days. It's a great anti-viral and anti-bacterial.
There's also a condition called Vitiligo
(explained pretty well here
and here with some low-res pictures
) that might cover what you're seeing with your aussie, and with my staffie sometimes. Apparently there's no treatment, and pigmentation may return or it may be permanent.
