So I've now got some cell-phone photos of horse #2, and while they're not perfect, they do give us a little more information. Here's the two side-on photos - I've cropped and enlarged so the sharpness isn't perfect, and have also straightened the photos:
Here's what I see so far while trying to look through the paint camo - not too bad: top line's pretty good; she's a bit long in the back but not horribly so; a little straight behind but again not terrible; shoulder, head and neck not too bad either; and good overall balance although she's fairly lightly built.
Here are the hind legs from the back:
A little cow-hocked, but again that's not a huge defect - but I'm not liking how she's weighting the outside edge of the left hind. And here are the front legs:
Now leaving aside the trim, which looks a little weird to my eye, and the fact that they've managed to put her left front in the floor drain, which affects how she's standing, the left front looks a little odd to me. And remember that the trainer said that she paddles in front - this usually means either that there's a problem with how the horse is put together in the front, or else the horse is traveling oddly to avoid weighting a foot in a particular way that may be uncomfortable. A horse that toes in in front will often paddle.
So now that I've got a question, I had to go back and look more closely at the other photos.
I may be imagining things, but I think there's something funky about that left front, and I don't think it's just the floor drain. The angle of the pastern is straighter than the right front and from the outside (last photo) the shape of the heel on the outside seems a bit odd. And those horizontal dark areas about 2/3 of the way down her front feet could just possibly be event lines - or it could just be dirt.
I'd be interested in what you think about this - am I just imagining things?
