Most of the sites I've looked on, say smutty/sooty buckskins have dapples. And she does, oddly enough. When we first went to look at her, she didn't have any dapples what-so-ever. The day I went to get her, her dapples have appeared and have stayed ever since.
She also has a very distinct dorsal stripe. But I also read that counter-shading is a form of the Sooty / Smutty gene which mimics the dorsal stripe associated with Dun. Sites also say that their sooty color comes and go's with the seasons. Her previous owners say that in the summer, she is more of a golden tone. Let me know what you guys think. I'll post some pictures that were taken for her for sale ad, which were taken this spring and then some pictures of now.
The first two are from her for sale ad.
The last two are from the day I got her home. October 1, 2010
