She is a fine example of how well built for general riding purposes the Appalousa horse can be . She has , what I call, the "Subaru of horses" build, meaning, drives well, rarely breaks down, looks pretty nice and has all wheel drive to get you where you want to go.
Her back IS long, but as said, her hip is angled so well, sized well (not as big as a QH type, tho) her neck is long and counter balances the longish back, and shoulder is neither upright nor laid back . Pasterns are short enough to be strong, but are not posty and are correctly angled. I bet she rides real comfortable for you and I bet she would throw a really cute baby, not that I am suggesting you breed her. Even her face is feminine and appealing. Better hold on tight to her leadrope!
