What a unique build! She's only 12" at the withers? She looks so big in the pictures...If she's as big as the pictures make her look, I say:
- Cardigan Welsh Corgi (height, stature, and legs)
- German Shepherd (common breed - her coat color is very indicative of a GSD)
- Golden Retriever (the ears, the soft expression, the long coat)
- Husky (coat texture, especially the ripple in the 3rd picture, and curled tail)

If she really is only 12" at the withers, then I'd say something like Corgi/Dachsund/Husky.
