Maestoso's are powerful horses with a long back, extremely muscular cruppers and heavy heads. Neapolitans retain their original tall, more rangy appearance and they have graceful movements and high action. Pluto's, their ancestors from Spain and Denmark, are sturdy horses with a rectangular build, ram-like heads and a high set neck. The Siglavy's typify the Arab Lipizzaner with aristocratic heads, a slender neck, high withers and a relatively short back. In addition to the stallions, there are 18 mare family lines.
Every stallion has two names, the sire's name and the dam's name.
This explains the name such as Pluto Theodorosta. Grey is the dominate color, of the Lipizzan today. Since white horses were preferred by the royal family, the color was stressed in breeding. As late as two hundred years ago, there were a great number of blacks, browns, chestnuts, duns and even piebalds and skewbalds. Today non-white Lipizzans are a rarity and only now and then is a black or bay found.
