Actually, from what I can see he is exceedingly well built. I like just about everything a bout him. I have some question about his front right and left right being toed in a bit, but it is hard to tell , 'cause he might just be twisting as he steps a bit.
He has great big knees, great big hooves. short canons all around, good straight front legs, excellent shoulder angle and lots of bone there. Well sprung ribes and pretty good heart depth. back to neck raito good, though neck is a bit on the short side for the arab "look", but not a problem for his usefulness.
He is really a very well built horse. Not gorgeous, but built to last! He the kind you want.
