It's possible she could be bred, but there is also the possibility of a risk. I know there are some pet/show breeders who will actually wait until close to a year, sometimes longer, to breed females even for the first time. However those breeders also know their bloodlines can handle it. Without knowing... you can try it, but be prepared for the worst. If you are too attached to her to lose her, you are probably better off waiting for another female.
