I'd say she just acts more "aware" of it than the other females I've had fixed.
As a "for instance" our older GSD Hunter came home from the vet and could barely walk, or acted like it, the morning after his neuter. But if he needed to or wanted to he could run. The girls we've had done were moving around really well the next day, as if nothing happened.
Twila has interest in everything and the other animals but is walking a tad more gingerly and is a bit more quiet than before the surgery. Just now she went and found a tennis ball for herself.
She's just moving a bit slower than prior to the spay. Oh, and it was just yesterday she had the surgery.
The only true wisdom is in knowing you know nothing.
