so you would not realy know what day into her season she was?
Male dogs seems to be able to produce stud dog or not.
On my cavs you can not tell they are pregnant til about 6 weeks.
The vet can scan her so you will find out the truth.
My cav boy is only 9 months and when of my bitches are in season he is crying to get at her(like got one in at the moment)i hope shes not as you were waiting for clear health tests before you bred from her.
Will keep my fingers crossed for you.
