carol,
where do you live ? I live in southern chester county, PA and I
had a TWH and all the vets i used did not know how the walker's locomotion
worked. ( i live in TB, quarter horse country) I had 6 vets look at him. He
ended up having lyme's disease and EPM.
Just wanted to throw that at you because his hind end issues could be
something totally different. My TWH foundered also and they blamed it on that.

Michelle
