There are lots of charities in Europe taking care of Spanish dogs, as they are treated pretty badly - especially the hunting breeds (sighthounds), like podenco (comes in all sizes and colors) and galgo (a little smaller than a greyhound).
We also have a possible Basenji/Terrier (Yorkie) mix. I've had some doubts, but seeing this picture of Rosie, I can't help but see my Rebel. Such a great looking dog, and if she's anything like our girl, you're in for a treat!
I don't see basenji in your rescue - she is a very cute doggie, and there very well may be feist in her. A DNA test would tell you everything and it's a good investment; it would help you know her personality traits and identify her behavior as well.
