All I can say is, you can't keep a good dog down. Sepp can still leap for his toy. Maybe not as high as before - but maybe in a year that will be a different story.
As far as meds go, he is still on vetprofen/tramadol only, 2x a day. Stopping the gabapentin didn't seem to make a big difference. I'm not sorry I gave him the gabapentin, but I'm not really sure that it did much of anything, other than make me feel better.
