Charlie had told me that they breed Tinkerbell once a day for 7 days...I guess that she take more than others???
Anyway, maybe this is why she produces such large litters. I think...IMO...that if she was only bred for 3-4 days that her litters might be smaller and she wouldn't have this problem.
With the stud dog breeder, breeding for 30+ years, you think that she might know this?
