Greyhound-specific color genetics

What on earth is THIS?!?!?!?!?!?!?!?!?!?!?!

I'm no color expert, but I'd call it reverse ticking.

Apparently it happens in greyhounds but I don't think the genetics are described. It's discussed briefly in the middle of this page:

Oh, we've talked about her before on Greytalk. She's got white ticking and is gorgeous. We found another dog that was called "dun" which turned out to be a chocolate brown. There were a few other really interesting colours that were brought up.

what is the genetics of it? what loci produces "reverse" ticking?!?!

 

[krissy]

Sorry, no clue about the genetics of it.

Here's the link to her thread on GT: Speckly Hound

And for the dun greyhound: Dun hound

I don't think anyone knows that yet.

That is beautiful.

She looks like a fawn!

I'm interested in how stable the color is. Do they start out with spots? Do the spots increase with age? Does the dog eventually turn mostly white? Does it spot out to a certain point then stop?

This might sound weird, but my knee jerk reaction when I saw the pic was to think that it's autoimmune. No evidence whatsoever to base that on though.
