^^ Um, Dash for Cash bred top and bottom according to the sale ad. That means this horse is racing bred, not
halter bred at all
. Also, not significantly over at the knee. Slightly, yes, but not significantly and not in a way that will limit his ability.
As for his hind pasterns, they are absolutely fine. Horses carry 2/3 of their weight on their front end, so it stands to reason that there would be more angle in the fronts than the hinds. This horse is no straighter on the hinds than any other horse.
And, as you can see from the picture of him being ridden in the sale ad, there is no lack of flexion in his hind pasterns
He is a little bit lighter in bone that what I like to see, but 99% of quarter horses are
these days and they get along in performance disciplines just fine. Sometimes I think my eyes are just biased from so many years of looking at Mustangs and Draft crosses.
Also, as the OP mentioned, he desperately needed his feet done when she got him. That alone can change the appearance of the whole leg.
OP, I really like him. He's a little long in the back and a little light on bone, but if he's got the speed and the heart, I think you could go far with him.
