We just had Autumn spayed three weeks ago and there were no complications. She has reacted badly to vaccinations in the past so we were very nervous, but she came through with flying colors. The did a pre-op blood test for kidney and liver function. They also sent us home with 10 days worth of Clavimox. She had no fevers or anything. The most stressful thing was trying to make sure she didn't jump around and that she didn't yank out her stitches. Her surgery was on the 21st and now the incision site is healed and her hair is growing back. We went forward with the surgery because the heat cycle was very stressful for her.
