Not sure exactly how much or when (I was out working in the yard for 3 hours), and the vet says ther is not really anything they can give her, just make sure she stays awake.
Although I'm worried, she's also funny. She's overly affectionate and appears to have lost all self control--she will normally sit quietly next to me while I'm eating; now she's literally climbing all over me. Her bark is also much more high pitched than normal. I wonder if this traumatic for her to feel this way.
