The pics with Santa that people have of their pets amaze me, because if we handed ours over to Santa the reaction would be "if you touch me, I'm screaming!". My wife's sister has a French Bulldog/Pug mix, and he's all over Santa, striking pose after pose, totally enjoying himself. Our mini Rat Terrier did sit for a pic once, but he wasn't happy about it, but none of the Dachshunds want anything to do with it.
Anyway, nice pics! I've never had a Whippet... are yours older, or is the face coloring normal in that breed? Our oldest Dachshund is 11, and her face started turning white when she was 5 or so.
