When I had Prue spayed about a year ago, I dropped her off at 8AM and picked her up at noon, the same day. She slept the rest of the day and was fine the next day. They closed her up with self dissolving stitches so she didn't even need a follow up. She had an E collar overnight but kept away from her incision, so even that E collar went away.

You might want to ask the vet if it is necessary for her to spend the night.

Good luck and keep us posted.

Also, Prue was happy to go back to the vet the next time, as they give her treats galore.

Her personality did not change. She stayed a PUP for another 10 months.
