Oops that last one got posted too soon

.
Caney is home now!! Surgery went well, she ended up having a lot of the gingival hyperplasia removed, in fact the vet had to spend so much time working on her mouth that she didn't have time to remove the hemangiomas on her chest and leg (it would have required more anesthesia and more $$, which the vet did call me to ask if that was ok, but somehow I missed the call

). But that is ok, we got what was most important. Caney was super hyped up when I picked her up but that adrenaline didn't last long, on the ride home she started getting sleepy looking and swaying back and forth like she was going to fall asleep sitting up.
I bought her some canned food and offered it to her when we got home, I can tell she wants to eat but her tummy is upset

she keeps going over to sniff it and then walking to the center of the room and whining.

I hope she feels like eating soon because I don't know how else I'm going to get her to take her pain meds! Should I give her something to settle her stomach or just wait it out?
