Oh, ok. Sorry I assumed things, then.
I got a female American Bulldog from the pound a while back(fostering)
Was told she was too young and hadn't been in her first heat cycle yet.
Took her to the vet and he said she was pregnant with 13 puppies, looked like she'd had a litter before, and he said she probably wasn't healthy enough to deliver them and live.
Unexpected pregnancies are so stressful
