The lipizzan is also a spanish horse this is why in Austria it is called the Spanish Riding academy. and when the spanish came to american they brought with them the horses. Some these horses got loose and the Nez Perez indians captured them and bred them for the color. There was an article in Western Horseman I beleive in 1974 about it. I also did my high school research paper on the appaloosa breed. Used 150 references and it went on to say that drawings of these horses were found on the walls of caves in China dated back to 500BC. Now I basically gave my age away.

Also I thought a jack was a cross between a ginny and a horse.
