Kirby seems to be doing well on his meds and herbs and his energy level is pretty much back to normal. As we anticipated, our biggest challenge is making sure he doesn't get overly excited or start jumping (one of his gleeful habits). Interestingly, I think he does sense an increased concern or urgency in our voices when we tell him to stop jumping. He's actually listening and stopping, for the most part, which is really, really helpful.
Baxter seems to sense that something is different. He has been different with Kirby -- sniffing him a lot, tolerating a little more cuddling, accepting when we're paying attention to Kirby. I was away working when my husband took Kirby to the vet on Tuesday, but he said that Baxter was just out of sorts during the hours Kirby was away. And Bax seemed genuinely happy when Kirby came home. Baxter has always been an extremely sensitive dog and I think he knows something is up, probably by the way we're treating Kirby and by whatever different smells and information Kirby is conveying.
The vet put Kirby on a low dose of prednisone to reduce inflammation and I think it is making him a little hungrier. He's now begging for food with much greater intensity and keeps going over to his empty bowl to lick it. Oh well, at least it's really easy to give him his pills -- wrap 'em in pieces of cheese and they go down in one fast gulp!
