You really don't want to pick her up if you can avoid it. You also don't want her to do a lot of jumping. She's just had the equivalent of a hysterectomy, so she will have a sore belly. She'll probably be a bit "off," maybe cranky, restless and want you to be in the room with her but not touch her. Don't take it personally if she growls or snaps, just leave her alone. Anesthesia can affect different dogs in different ways - just like it does people - and it takes a lot longer to get it completely out of the system than you really think.
Don't necessarily let her get by with bad behaviour; if she misbehaves walk off and ignore her, just understand that it's probably just post-surgery stress and the anesthesia.
She probably won't have a lot of appetite when she comes home. A little unsalted chicken broth to start, and add a few tidbits of cooked white chicken meat later. I'd even hold off on the dog food for a day or two, then re-introduce it to her in small portions throughout the day. You don't want to load her sore belly up with too much food at one time!
And have fun trying to keep her quiet for the next ten days or so . . .
You really don't want her playing any games that involve tugging until she's healed up.
