My bitch was bred 5/6 weeks ago. She was bred on the monday/wednesday/friday/sunday (monday mating was a slip mate) when she returned home after a week she had a green discharge for which she saw the vet the same day, was given anti-biotics and the vet said the infection would not have reached the womb or pups, it cleared up immediately. She was extremely tired around the 3/4 week mark, off her food completely. shes still tired now, nipples look swollen, but her belly looks pretty much the same as always. This was her first mating. Had her scanned at 5 weeks and vet couldnt see any pups..however ive heard most vets are pretty crap at scanning. she's due a scan again in a week now. Im in limbo! i think i will just be waiting to see if she pops any out or not! anyone else had scans that showed nothing and still had pups? the green discharge? Shes a Bullmastiff and just over 2 years old.
