Thank you for your taking the time to post the info. After contacting another Repo vet, I made the decision to work off of blood work to watch the red cell count amongst other things. I believe a blood clot broke loose or something like that, and as long as my bitch is acting normal, I am going let the uterus run its cource and hopefull it will be a self resolving problem. Today the color looked better and not as much blood with more clear mucus, and the blood work came back all in good order. I feel she is on the right track. My bitch is producing plenty of milk, in fact, she has taken in a singleton to feed and he's now FAT. Next time I will plan a C with progesteron testing and maybe an ultrasound to see the heartbeats. Thank you again!
