Pintaloosa is not a breed.
You mean Chanti is a grade horse that is a cross between an Appaloosa and a paint/pinto.
That's getting a little petty. Sure, it isn't a breed, it's a cross, but really, did it require mentioning in this particular thread?
As to Appaloosas being a stock horse. If we look back a hundred and fifty or so years ago and think of what a spotted horse might have been used for, I think you'll find that they were pretty much jacks of all trades. They were likely used to hunt off of, pack belongings, the occasional match race, etc. Basically, the beginnings of most North American breeds.
As the Appaloosa was developed, they were bred in the image of what people wanted. Which in general seems to be stock horses.
As far as breed improvement goes, the infusion of QH/Tb blood has improved conformation, performance and aesthetics. This ought to be considered breed improvement.
While the foundation Appaloosas were the start of a breed, horses should be bred to improve upon former generations. I believe outcrossing has done just this. Posted via Mobile Device
