Thanks for all the info too. I forget that they do use make up on the horses for show and picture purposes, which does make a huge difference. I know someone who breeds, trains, and shows halter Mini's, and I watched him shave a rather fuzzy mini with a huge winter coat. He was doing a show that weekend, and man, the difference between the horse with the "normal" fuzzy winter coat, and the horse all shaved up, you almost wouldn't think it was the same horse. So there are many different ways to make the horse look different than it maybe really is.
I tried to ask someone who used to show Arabians, trains them still but no longer shows, about the whole dished head thing, and I loved my mare so much that I want to find another Arabian like her, I wanted to know what type of breeding she was, I.e. Egyptian, Russian, etc. The answer to the dished head thing wasn't really an answer at all, so I've been kind of wondering myself, I thought that the jibbah was a very desired trait if the horse had it, but I got a "what's that, it's got nothing to do with the dished face" type of answer which made no sense to me. He also said that my horse was a "domestic" bred with a little Egyptian I believe, which leaves me scratching my head as I've never heard the term "domestic bred". But anyways, just goes to show you that everyone had a little different opinion, or explanation, and there are many different types out there, which is the same with any breed. You can get TB's that look more like Quarter Horses etc. People always thought my Arabian was a Quarab. They had a hard time believing she was purebred, as they were used to the skinny, very refined Arabs. Anyways, great information.
