Did not know she was pregnant. I have two males and I guess they got her while I was at work. She showed no signs of pregnancy, no weight gain nothing< thought this morning she was having kidney stone trouble called the vet she was shivering and panting, they told me to get a pee sample so i took her out side and she kept licking down there so i looked at her peepee and their it was a bubble, OH MY called the vet and told them never mind she is having pups. Had one right away, It did not make it tryed for 45 minutes, next one was fine, it has been two hours now still feels like a pup in there but i have thought this before, How long should i wait inbetween pups before i worry. She is acting calm, I keep feeling her tummy one minute i think i feel a pup the next i am not sure.
