If she seems healthy, defenetly get her spayed...
Believe around 11 months is a decent age. (body should have
reached sexual maturity by then).
I use to have a female and didn't get her spayed till an
older age, by that time she was getting uterine cancer.
(beginning stage I believe). Vet discovered it when spaying
her and felt assured he got it all. They claim every heat
cycle increases the risk for this type of cancer in female dogs.
So, yeah, take no chances, defen. get her done soon as she
is age ready. Make a happier/better pet as well.

Blessings.
