I would have to say that the most overlooked fault in Minis is a poor hindquarter in general. yes, I see lots that are camped out, and many/most of those do have an overall poor hip otherwise. Often you'll have a horse with a nice front end, and then there's that rather awful hindquarter just kind of poomped onto the end of the horse, looking like it really doesn't even belong on that horse. Sometimes it's a real slack rear end, often it's a rather thickset, bulky looking butt that in spite of it's bulky appearance comes with a very short hip and low tailset. Then there are the thin, straight stifles. Sadly, so many people don't seem to recognize this fault at all. Many cannot recognize a poor hip when they see it, and even more don't know what poor stifle conformation looks like. Worse, there are those that don't even look at the rear end. They see a pretty head and a nice neck, and I honestly think some of them don't look beyond that.
Stretching will not help with poor hip conformation--trust me, I see many horses stretched out & they actually look worse stretched than they do stood square. On the other hand, stretching will not ruin a good hip--a good hip will look like a good hip whether the horse is square or stretched, though over-stretching is not so flattering to any horse. Stretching does not make a horse appear to be camped out if it isn't, nor doesn't it hide camped out conformation. If you stretch a horse that is camped out, if you run a line up the back of his legs, with that line touching the back of the fetlock and the back of the hock, that line will not intersect the horse's rear end. On a horse with proper hind end conformation, when you run that line up the back of his legs when he is in a stretched pose, the line will always intersect the hindquarter.
