I know how you feel. Maddie had to have 2 hernias removed plus got spayed. I was so scared. She wasnt even 3lbs either, so that made me even more scared. Make sure the use the gas, and make sure to have preblood work done first. I'm sure she will be just fine. But its natural to worry. I'll keep you guys in my prayers. Maddie was really sore when she got home. its was sad.
