My first and second horses were Arabians, and I LOVED them! (They have since died at the ages of 24 and 26). But I have a real soft spot for Arabians and would definitely own one again if a nice one came along.
The first one was fairly bomb proof and lazy. As a matter of fact, I had to work hard to get him to move out at all. Perfect beginners horse. Unless I put guests on him, then he would have energy and run away with them! But for me, well, I had to go to great lengths to get him to move. I like to say Gucci taught me everything I know about horses.
My second Arabian was more typical and firey. He had lots of "go" and could hardly keep his feet still. He was a lot of fun to ride once I learned that he wouldn't do anything too naughty. He was actually a very safe horse, I think I only came off him once in the 10 years I owned him, and that was because the saddle slipped. (I always assumed he would run off and leave me for dead, but he didn't, he stayed with me). He was a blast to ride! He had some moves I would call his "airs above ground." But he never bucked or did a full-out rear. Just little levades. Ha ha!
I think I read somewhere on this forum once that if you think you will like an Arabian, then you will. I think that is a pretty accurate statement. If you are already attracted to them and like their beauty and spirit, then you will like owning one. If you just want a horse to behave like a robot, then you should look elsewhere. They are not bad horses, they just have more personality and sensitivity than most. They appreciate a sensitive rider and don't do well with folks who "want to show them whose boss."
I've always been understanding and admiring of "hot" breeds. Not horses that misbehave or are disrespectful, but horses that have spirit and personality. That is what makes horses beautiful to me. I have a Fox Trotter that I'm sure would drive one of my friends crazy (she has the most well trained, docile QH's I have ever met) but that's okay. I seem to get along with horses with "go." I have never owned a TB, but I had a friend who owned one years ago and I loved him as well. I like docile, calm horses too. They are great. But I also seem to get along well with horses that other people find annoying!
