First off, thanks for all the well wishes. As you can see, Louise is feeling a LOT better in this photo. At this point, she had finally been able to move along some of her crap, but was still feeling pretty weak, and walking slowly.
Somehow, I never get tired of rewording constipation symptoms.
Anyway, as of today, Louise seemed to be back to her regular self, wanting to walk at full speed and happy to see just about anybody. We walked to the local Pet Store and the extra attention she got there gave her lots of motivation to keep going. She walked all the way home without assistance, and that's all uphill!
We just got back from her night walk and if I didn't slow her down, I'm sure she would have wanted to walk straight to the seawall and back. We have been careful to not let her overdo it too quickly though, so we settled on a medium-length walk for now.
