Brief update: the family is out of town, I backed out of going because I'd either be a bummer or I'd overdo it and hurt myself. So it's just me and the dog.
I'm doing fine, other than his surprise jumps onto me when I'm on the recliner - he always lands on a sensitive place, whether it's the incision area or... other places (he normally bugs my wife or kids, since I'm the disciplinarian).
The dog (Charlie) is also doing fine, but is clearly frustrated by the fact that I don't want to take a hyper, surprisingly strong for his size dog for a walk while I'm using a cane and it's close to 100 degrees outside. Hence the surprise jumps onto me when I'm trying to relax.
