I also thought it was odd that she developed this habit but wasn't injured, that really caught my attention and I think she was indeed injured and that is the underlying issue.
Sorry for the bad punctuation. I have been in a hurry today and got going on the subject without thinking about how hard it could be for others to read. I will work on that :)
I also disagree with most people`s perception of Arabs. I have been riding Arabs my whole life and I am use to the automatic response about Arabs being flighty, skittish, crazy, hard to handle, hot, temperamental (I'm sure you know the stereotype). I was told when I got my first Arab at 11 that it was a stupid choice because an Arab was all of the listed above and more. But my gelding is the best choice I could have ever made. I automatically expected the Arab judgement so I thought I should throw in that she doesn't have the "typical" Arab behavior that most people expect. But yea, it`s not my judgement, its others, I was worried people would automatically assume the "fear" was due to breed, which obviously isnt :) In my area we have lots of QH and anytime we bring our Arabs or TB`s into a subject, cow people make the assumption. Sad part is I'm a cow person myself LoL but I prefer my gelding any day over a QH (not that I have anything against them but my gelding is pretty amazing LoL)
Hope this clarifies a bit more and is easier to read than the last post :)
Let me know if I can clarify anything else...
