Dr. Murphy still thinks that Snoopy is progressing, even if all we can do is walk him. She says (rightly so) that his left side had atrophied quite a bit. He needs to both rebuild the muscles and re-gain flexibility.
As Brigid says, "I'd like to see his butt cheeks look more even before we start trotting."
According to her, we're a long way from calling him permanently disabled. So we're walking him every day and having chiropractic adjustments and keeping our hopes high.
After all, what else is there for us to do at this point?
