Hi,
My little girl is also CoCo!
We had her spayed at 7months and she also had teeth pulled. Just make sure she doesn't have food or water for about 8hrs before she goes in She will be sleepy when you fetch her, keep her warm and comfortable and give lots of love and some water. Don't let her jump on & off beds etc. for a while. I'm sure the vet will give you instructions.
She might be a little sore for a few days, but my baby was playing with her brother quite soon after her op.
Good luck and prayers for the little lady.
