I just posted this in
equestrian but if you all are anything like me, you may not be reading much in
equestrian these days. So, I thought I'd share here as well.
I came across a very thorough and good conformation article on wikipedia that describes several conformation faults and provides pictures of many of those faults. It's also very well organized.
