first of all -
I am so sorry that you are dealing with all of this. It has to be so very hard dealing with this but Missy will be great through all of this. She will be good as new. I can understand you wanting to wait in getting her spayed and if that is the case then I would wait. Let her heal and let the two of you spend some quality time together. There is no time table to have it done so just take it slowly and enjoy each other. She knows that you love her very much. Just take it one day at a time and all will be fine. Hugs!
