Buffy is home

I just brought Buffy home. She looks like she's in a lot of pain. most of her back left side is shaved and her stitches are huge!
I'm trying to keep her from moving around too much.
I was sent home with three different kinds of medicine: Two painkillers and an antibiotic. I was also sent home with an instruction booklet of all the things I am supposed to do for the next two months. It includes things like icing her knew, heating her knee, and exercise plans. She is going to be hurting for a long time I think.
