I took Wally to the veterinary neurologist yesterday, and guess what? He doesn't have to go back for several months. The vet was pleased to see him up and walking, even if it's an unsteady effort.
In the afternoon, I took Wally for a short walk. Even though it wasn't much more than a trip across the street, moving one house up and crossing back, he was exceedingly happy to be out and about. And even though I had to carry him part of the way back, I was happy to see him enjoying himself - and walking (relatively) very far.
Wally and I took an even longer walk today - nearly three times yesterday's distance - during which he met another dog as well as taking care of his doggie business, and he's been tired ever since. And it's possibly just wishful thinking on my part, but he seems to be starting to regain slightly better bowel control, which would make me happy indeed. All things in good time, right? Let us hope that it is so.
