Since you're from Germany, I can only throw out some guesses (which may not be very accurate LOL).
You are correct in the PM you sent me that the color is JapaneseHarlequin. She may have some type of blue eyed white breedalso mixed in (which the white snip on her nose indicates).She looks to have Dwarf mixed in because of her short, dense bone andcompact type.
Could even be a Lionhead mix (without the mane).
