Glad to hear it isn't severe. The main things I was concerned with when spaying Lulu was doing the pre-op bloodwork, making sure they use the best anesthesia, & that they used an IV with fluids during surgery as well as using a warming table. I didn't know that IV fluids aren't commonly used during spays/neuters around here. My vet said she would recommend one for Lulu due to her size, but I was going to request one anyway.
Good luck with it. I know how nerve racking it can be. Lulu was spayed Dec 7th & then had LP surgery Dec. 28th. I was a ball of nerves both times.
ETA: this is a good read before surgery.
