It is, it's very discouraging and frustrating seeing her like this and not knowing how to help her.
Poor Rudey, dealing with similar things.
I'm so sorry there was no decent help available at for him at the end. That must've felt terrible for you, not being able to get him proper help.
With Sophie we've never found anything that could explain it, you're right, though we're looking into arthritis now, of course. Still, since her x-rays last year were fine, that can't have been the cause all along when she's been doing this for years... I've started a thread about it before, but I think I'll make another one, just in case someone knows anything.
Thank you for the vibes for her, too, j&b.
