Lucy is back to normal.
Gillis is okay too. He's a bit dazed and confused sometimes, but is very happy, and most of the time seems to know what's going on, and how to get around. He's good on level ground, but has some balance difficulties in rougher terrain. He's having a bit of difficulty with coordinating his back legs and needs a bit of help negotiating the porch stairs sometimes. He still "assumes the position" to have his back scratched. We'll take him back to the clinic this week for further assessment.
Thanks everyone for your good thoughts for him. I believe they helped.
