Hi, I can help you with your question today.
We need to confirm if she has any more puppies inside.
To do that, she needs to have an x-ray.
If we find another puppy, we can try to help her with medication and a lot of lubrication.
If she has a puppy that she cannot get out, she could need surgery.
Another possibility is that she has a problem like hypocalcemia (eclampsia).
This is more common in small dogs, like Poppy, that have large litters.
This can be detected easily with some blood testing.
Please let me know if you have further questions. I am happy to continue until I provide the service that you seek.
