Recently spayed pregnant dog experiencing abnormal bleeding

[lucydc]

My 2 year old female dalmatian was spayed on the 10th of October. She had just completed her heat cycle and was pregnant. (This was her third heat and she has birthed a litter after both of her previous heats, unintentionally.) She hadnt showed any signs of pregnancy yet and we were not aware until they notified us after the spay was complete. It has been 9 days. About 2 days ago, she started bleeding from her vulva. It started as a stringy mucusy blood, almost like the blood when she was in heat. HOWEVER, today when returning home after about 4 hours of being away, there is numerous blood spots around my house. Also there is a few clots of blood around the floor. She has obviously moved a lot because the spots of blood are scattered. We called the emergency vet hotline of the spay and neuter clinic and she told us to wait until the morning and take her to the vet. Lucy, our dalmatian, isnt completely inactive. I left work when I heard about her bleeding and she greeted me like she normally does. The blood is now a lot more constant than as if she were in heat. She is dripping blood and Im not sure what to do. We put her in the laundry room to try to contain her but she began to shiver quickly.
