I have a Welsh Sec D who last year got diagnosed with arthritic changes in the back right hock. He was 2/10's lame & got treated with Tildren.
For the past two weeks he has seemed "wobbly behind". He isn't lame. Just doesn't feel like he came keep his back leg coming through. My dressage trainer has sat on him & he does it with her too. He is tail swishing too which he doesn't normally do.
I have tried Bute to see if that would make a difference & it hasn't. He is on Synequin anyway. he has had heat in both his hocks although last night it didn't seem quite so bad. I have phoned my vet who will be out on Monday.
I have had his back done, teeth done etc.
