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).
I think I see some of the basenji ears, especially in the second picture. I just want to grab them and rub them good! :) It's most likely that there is at least a black lab there too. Also it may be not the first "mix". If it is a generation over there may be more then one mix in there. But either way, Lilly is adorable! :):) It's awesome that she has a good forever home now.
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.
