We will keep our fingers crossed that nothing is wrong and it is just one of those strange unexplainable things. We worry so much about our pups going through this surgery but we pretty much take for granted that when it's all over everything returns to normal. I certainly hope that is the case. You have certainly come to the right place for advice. Most everyone here (I hope) has neutered or spayed their pet so maybe someone can add something. On a lighter note...maybe she was dreaming she was outside in the yard with some delightful smells and just let loose! Seriously, I hope she will be just fine.
