His hindquarters are asymmetrical, you can see it
standing behind him, and also on his upper shoulders. And
they're "opposite" sides, if you follow me. It could be from him carrying
himself wrong - I really don't know. It could be my riding -- I don't
post -- normally I stand in the stirrups, and post very, very little.
I could be riding crookedly, too, you know -- this is quite possible, and in
fact maybe even likely.
There are so many things to consider. But
again, the stumbling and falling to his knees twice while I was riding him,
at a walk (!), were what caused me to take him to the vet to start
with.
Hang in there...keep the faith that you'll figure out what's wrong with
your boy and fix it. Where is the asymmetric muscling? Hind
quarters? Up high or down low? Any chance that could be due to a
chiropractic problem, maybe he's been carrying himself crooked due to
that? Any old injuries you're aware of? Do you change diagonals
frequently when posting? Just brainstorming here...
