I Need some help! My dog apparently broke out of her crate during her heat and mated, and she is not spayed. Yes, I had planned on getting her spayed, due to covid, it was delayed. I made all attempts to keep her away from the male, however I failed. I took her to my vet, and they did a ultrasound and found fluid in her uterus, and want to do another scan in two weeks. Is it possible she has a infection? Is this a early sign of pregnancy? My vet only told me there is a 70% chance of pregnancy, and I am highly nervous. Has anyone had anything like this happen?
