Good Luck,
I'm sure she will be fine.
My bitch had to have an emergency spay 6 weeks ago after developing pyometra,but that was a complicated one,but she came through it fine.
She was on metacam for pain relief and AB's.They did give her a collar to wear but we never put it on her and she never bothered with her stitches.

She was on limited exercise for 10 days,two short walks a day of 10 mins,then we started building it up again.She wasn't allowed up the stairs etc and we were told to take out to the garden onlead,(we never did this because otherwise she wouldn't have gone to the toilet lol)

Just take things nice and easy with her,fingers crossed Keep us posted!!!
