Rosie was spayed yesterday. She is eating real well. As a matter of fact I just fed her and her food is done. She has been licking her bolw that no longer has food for the past several minutes

However, she's not drinking. I mixed some v8 splash with her water and she didn't drink it. Now I have some oj mixed in it. She drank a little, but hardly at all. Also, she has not pooped since I have brought her and only peed last night at around 8. Anyone have any clue what I should do? Should I not be too worried about it? Btw, other than that she is doing real well. She has been wanting to sleep under our bed and couch and she has never done that before
Thanks in advanced for any advice on what to do.
