Both are weedy looking IMO. Both are slightly back at the knee. Horse A has some serious front leg rotations going on and horse B has bench knees. Horse A is sickle hocked and built down hill. Horse B is straight and post legged behind.
Horse A has better bone than horse B and larger roomy hocks. Horse A has more butt than horse B.
I disagree with them bein bench kneed and back at the knee till I can see them on hard ground-- im thinkin the tilled up sand theyre standin in is makin em look that way.. definitely wantin to see them on concrete. :)
