This is Dora, a silken windhound. The breed resembles a small borzoi or a whippet with a long coat. This makes sense as the two major ancestors of the breed are, in fact, the borzoi and the whippet. The colors seen in the breed are also just as varied as those seen in these two ancestors. So, what's her genotype?
To begin, Dora is most likely atat tan pointed. The pale spots over her eyes and on her cheeks appear too well-defined to be graying from old age and the location fits with what is to be expected from tan points. They also appear to be tinted ever so slightly cream.
In combination with the above, the red in Dora's coat must be extremely diluted to appear so white. As such, Dora is likely cpcp extremely pale red.
Dora also has a lot of white on her. This is caused by the Spotting locus, and because of how little color she has on her, I suspect she is swsw extreme white piebald. It could also be possible that she is spsw (piebald carrying extreme white) with a lot of modifiers increasing the amount of white, but I find it more likely that she is swsw.
Last, but not least, Dora has ticking spots on her legs. Ticking does not appear to be all that common in the silken, so I suspect that Dora is most likely Tt ticked.
So, that's atat cpcp swsw Tt or extreme white piebald black and tan with extremely pale red and ticking.
