Aww, I'm sorry.
I felt the same way when Ellie was spayed.
It seemed like I did the wrong thing but it did get better.
If she didn't hunch over on the meds, maybe she needs them still.
The not remembering tricks thing is concerning because it has been a few days. If that continues I'd talk to the vet.
Is she on antibiotics?
Are her gums pink or pale-white?
