males have been known to mate at 7 mos. but, I don't think you can register them before 9 mos.
As far as your female, how old is she, and how many heats has she had? You don't want to breed her before her 2nd heat..Also, what size are your female and male..?
Here's a website that tells all about the females heat cycle
