I think she said it was a first season, so I cerainly hope it wasn't planned!
There were two posts, first one as guest!
Bitches can actually be spayed at any time, but vets like to do it best at the quiescent time. I had one of my bitches spayed at the same time as her C section, as it had gone wll, and vet could see no likely problem.
The Uterus would not have enlatged much in the first part of pregnancy, especially at the pre attachment phase, so would be sfe to spay. bitches that are spayed in rescue centres can be at any stage in the reproductive cycle, inclucing early pregnancy when they are done. the vet would only know once he started!
