You still need to do the F1 cross first so that you can, in the coming offspring/grandget have the arab blood farther away.
Re: arab crosses approved with Old/NA. Well, one problem, no matter how nice a horse is, people still have to know it exists. I have known breeders who wonder why they can’t sell anything - but they don’t show the horses, and/or they don’t advertise. Also more than possible that this breeder you’re referring to just was not marketing the horse to the right audience. I think WB/arab cross breeders would benefit by marketing these horses to people who already have arabs/half arabs, rather than warmblood people. There is certainly a ready market for them - now whether the person in question exploited this market or not is an entirely different question.
Hunters and Jumpers that are arabian - while I agree that they are simply not the breed of choice, once again, I suggest marketing the horses to the arab market rather than the hunter/jumper folks. There are a few high quality hunters and jumpers in the arabian shows, but not nearly enough. And the high tail will never be in style in the hunter world (some of the arab stereotype of being poor jumpers can be overcome with the right horse - but once again - they have not been bred for decades to be good jumpers as most warmbloods have).
About the Arab and Barb - I would be interested in your source, for this. I’ve never heard that before and would be interested in reading the article.
Re: show horses. In any breed, there will be good horses and there will be bad horses. There will be nutcases and there will be quiet packers. That is an inescapable fact. Even the ‘wild’ halter horse frequently goes onto be a wonderful performance horse and are perfectly easy to handle around the barn. I would venture to say that of any breed that has halter, arabians have the most that go into performance. I can think of about 75+ horses off the top of my head that were successful in halter at the regional or national level then went on to also be successful in performance. I do think that the PERCEPTION of arabians is that they are crazy and stupid from halter classes. And the ‘pose’ doesn’t help, either, although at least people are working on changing both of these things. Although I guess I find it kind of funny that someone remembers the 10 or 12 halter classes at the average A show more than the hundred or two hundred performance classes (with about a fourth of those being youth classes! :lol: ). Oh well.
