I don't think she has any Arabian in her, honestly I have no idea what breed she is, a mix of some sort too heavy of a build I'd say
Unfortunately I don't think I will be able to get a video :( My cell phone is the only thing I have that can take a video but I could try sometime if I can make anything out I will post the video but I can't promise anything
I'm afraid that is the only picture of her that I have right now but I will try to get out to take a few pictures soon.
I would say that she does pronk some, she does hollow her back, it threw me forward and I had to keep fixing my position. Her head was really high, I was sitting up starting to collect the reins and she did bring her head up to smack me in the face. I have to say though asking for her to bring her head down was not what was crossing my mind when asking her to slow down so I will work on that
