It still looks like he slightly favors that arm a little bit, but he is now bearing weight on it. I canceled the vet appointment for now, I'm gunna see how he's doing later on.

This is making me think it could have been something neurological, such as a minor stroke...
Most strokes either kill them or cause perminant paralysis. Watch carefully. I would have taken him in anyway just to be sure.
