I'd be guessing, but they looked premature...if born on schedule, then it looks like they simply quit developing in utero at some point. How sad. Was both litters to the same dam? Maybe she can't maintain her pregnancies anymore due to an infection or something. It happens to people. Thyroidism can cause human babies to stop developing and die in utero....she should have the dam thoroughly checked, and tests done on one of the dead babies. |
