A friend is involved with rescue and they have an injured female dog who was C-sectioned to deliver her near term pups. At the same time as the section she was spayed. Now I'm confused because the fosters and rescue people were talking about the Mum dog's milk not coming in and now it sounds like they have given up on that. But, could it? Could her milk still come in even after she's just been spayed? Would it last if it came in?
