Thanks again everyone.
Things seem normall-ish (I don't even know what normal is at this point!) today. A better start anyway. Pooping outside again, going around the block (and extra steps this morning) normally. Standing normal on return. Regular-for-Rocky energy. Last night we did some back leg exercises.
Yesterday morning he pooped while I was putting his boots on :P And honestly, he didn't seem to know it was happening at all.
We have laser on Thursday and the vet on Friday so I can discuss if there is anything we can do that doesn't add a ton more money.
