Never been through it, so no help there but lots of girls on YT have been spayed an ddone just fine.
It shouldn't be any worse than that. Beyond regular surgical risks which are very small, I don't think you have anything to worry about.
I did a search and got lots of results on YT.
Instead of using the search at the top of the screen, use the one at the bottom. Don't forget to select "Yorkietalk.com" instead of "web".
