Taffy has been super good lately. Her rear legs and her hips are much better. I was thinking she was rallying because dogs often do that at the end. But then I realized--since it's her "last days," I've been feeding her table scraps, as well as locking her in my ofc so she can eat her regular food, so Starbucks doesn't eat it (he's a terrible thief, and a pig). So ... she's EATING. Uh, duh. Doesn't totally explain why her rear legs are better, but it does explain her energy level. I am so relieved! I will sleep better tonight.
