and I definitely agree that there are no breeds to completely stay away from, as mentioned. I always hear bad things about TBs, but I have one and know several others and they're awesome, very sane horses. My guy used to be a lesson horse. And it goes the same for arabs, too. Don't let people give you bad ideas about anhy breed. It may be smart to keep in mind that those breeds are more likely to be more spirited, but that definitely doesn't mean that they all are. Just don't pay attention to breed for now, and look for a sane horse.
And again, definitely, definitely bring a trainer. Can't stress that enough, it's always a good idea to bring a trainer.
