I had my Snow spayed today. I had to let her go through one heat due to a lack of funds. After the spay my vet called and told me she had Pyametria and that it was a good thing I spayed her today because it was bad and she would have been very ill very soon. She seems to be taking a long time getting back to herself. Could it be due to the antibiotics they had to give her? I'm slightly worried.
