Okay, I think it's safe to say she's feeling better. This morning she was frisky and played with me all on her own! She likes to "talk" which is a weird combo of barking/growling/and other vocalizations when we play and she talked!

I tried touching her butt and her leg and the leg got a nasty look so I'm thinking that's the culprit right now. (Thanks so much
Wylie's Mom for the explanation! It makes sense but the vet didn't tell me where she gave her the shot or that she may be sore afterward, like she did last time, so I didn't think it would hurt afterward.)
I've penned her off to eat, as she wasn't eating for me freed standing. (Though eating is ALWAYS an ordeal with Zoe.) Here's hoping she's so ravenous she'll eat!
I was freaking out last night and just needed someone else to say they thought it was all due to the shot. So thanks!

So far so good, here's hoping the rest of the morning goes just as well!
