I would recommend you hold off until around day 55-58 to have an xray done. An ultrasound although can be done earlier.. it isn't nearly as accurate at determining position and size of the puppies. It is best to wait and have an x-ray done. The x-ray cannot be done unti around 55 days or more because the bones have not calcified before then. The x-ray will give you an accurate headcount and will show position of the puppies and will determine whether they will be able to pass thru the birth canal. |
