They really are so very different the way they handle their surgeries. My male Ben, was neutered at 3 years old and he cried like a human baby the whole evening after I brought him home, and laid around til the 3rd day. My Candy was spayed early in life and barely slowed down after she came home. I had to keep glued to her to keep her from jumping and running the next day. Spaying normally is the more intense surgery. I had a previous girl, Kate, who had to be carried out to potty for 3 days after her surgery. None of mine spent the night. Instead, they came in early morning, surgery by noon or earlier,and home in the late afternoon.
I've never heard any of mine scream, yelp, bark, cry but not scream. You have to be the judge of what that means. If she only did it before as a way to show she was unhappy about getting snarled at, maybe she is showing you how unhappy she is at the treatment she got/surgery? I would of course watch her closely, check temperature, incision redness/signs of infection. Definately run her back by for a check if you think its needed. They should not even charge for this and it would give you peace of mind at the least and maybe head off a serious problem at most. I never worry about being too careful. anymore. I lost one girl and often wonder if I had been more aggressive with the vet, if I could have saved her. Better to not have that question even hanging in the air.
She is probably fine -- that first day is rough for most. Hopefully tomorrow will be better and then the 3rd day should be almost back to normal.
