Now I know what's been wrong with Jack. Battery change needed!
Seriously, it's been a long eight weeks, and there are probably another eight weeks of treatment to go, but Jack has been recovering from "non-infectious, mild meningitis". If that's what "mild" meningitis is like, I don't want to see anything worse. He seems to be making a great recovery now, but the task of "keep him calm" was the most difficult aspect of his prescription for a return to normality. Keep a Jack Russell terrier calm? They don't do calm. The hair won't start growing back until the run of cortisone tablets is finally over. So, yes, his back still looks like his "battery cover" has been removed (tapping of spinal fluid), and his tummy is still bare from an ultrasound many weeks ago now.
It also seems that the time I usually update this blog has been subsumed by medicating the dog morning and night. Every day, a different plan of drug administration must be coordinated, lest the wily Jack Russell suspect that something is afoot.
