well i had my cat "done" recently. Obviously different but alot of loves and hugs will be needed, and dont feel bad if your ignored for a while. Its common.
Just make sure there is somewhere comfy and peaceful for your doggy to sleep after coming home.
Also she might not make it outside to do the toilet but obviously after an anesthetic and being in a bit of pain you cant blame the poor thing. So maybe a few bits of news paper down would help just incase.
