I have just been looking at Photos of Cavaliers on another Site, what Long Backs they they have now-days and Shorter Legs from what the Cavaliers had in the Past.

This must be type of Cavalier that is wanted now for winning in the Show Scene, but they just don't look like Cavaliers any-more.

Just a Thought, could it be possible that this Type of Cavalier Back be linked to their SM Problem.
