Our bitch was scanned at 5 weeks and was confirmed in whelp however 2 weeks before she was due the Vet suspected that there were no pups. Around the due date we had her scanned and the Vet confirmed that there was no pups although the scan should black areas in her uterus. Today 1 week after she was due she has produced a discharge. The Vet has scanned her tonight again and suggested that she should either have an injection to abort what is left of the pups or have her spayed. Any advice would be welcome.
