Your bitch is way too young and shouldn't be bred from until at least another 18 months. Also she should have her hips scored as this is a major problem in this breed. Is she KC registered, if not enjoy her for the pet that she is. Please note DLRC papers are not the same.
If you have any queries go to her breeder, hopefully they were reputable. I have to warn you make sure that you go to a good stud dog who has been hip scored etc. as there are a number of unreputable breeds in this breed as of course there are in many breeds unfortunately.
