>>> im maybe going to go and look at him later this week.they say he is kid broke and is fast.he looks sweet.but how well do appaloosas usually do in barrel racing?would he do well enough so that I could compete in high school rodeos?
Do you have a pedigree for him, or know anything about his sire and dam?
Like I and other post-ers have said, his potential for barrel racing will depend on what he is bred to do, and what his ancestry did.
For example, here is a 2008 colt I bred--
His pedigree: Exalted Appaloosa
His dam has produced Medallion winning, ROM earning, and National Champion Western Pleasure horses. His sire was a Halter Champion who was sired by a National Champion Western Pleasure horse/National Champion Halter horse. His pedigree is full of Halter and Pleasure winners. This colt himself likes to travel "low and slow". (He was "at attention" in this photo.) He is not in a big hurry to get anywhere, never runs very fast for very long, seldom carries hid head above his withers. This is really really well bred Appaloosa, but he would not, IMO, be really competitive in barrel racing. He could learn the Barrel pattern and might be really fun to play around with as an all-around horse, but he is not bred to run fast, and doesn't seem, so far, to want to go fast.
On the other hand, here is this year's Non-pro National Champion Barrel Racing Appaloosa (Its called Camas Prarie Stump Race at Appaloosa shows, and its run horse against horse).
His pedigree: Zevis Rockett Appaloosa
This horse's sire was a race starter who sired ROM performers in speed events like Barrels, and his sire was a Thoroughbred race horse who sired stakes race winners and earners of millions of dollars on the racetrack. This horse's dam was sired by a really fast AQHA race horse who sired really fast race horses and also was well know for siring Barrel racers. This horse would be able to be trained shown in other events besides speed events, but I doubt he would be a very competitive Western Pleasure horse. He is bred to be fast, and he obviously likes to go fast and is good at it!
I hope this helps illustrate why its pretty much impossible to tell you what this Appaloosa you are looking at might be good at, without knowing more about him.
Appaloosas are pretty well known for being versatile and able to do almost anything (and/or being willing to try!)-- but to be truly competitive in a specific event, the breeding behind the individual can make a major difference.
