Hi, I had Sassy and Sadie spayed at the same time. Sassy rebounded with no problems. Poor Sadie seemed more uncomfortable, she was the one who tried to bother the stitches AND she was constipated. I used the canned pumpkin (no sugar added) and it worked like a charm. I gave her a spoonful 2 times a day and that did the trick. Luckily, she loved the pumpkin. I keep it on hand now, just in case.
