ACtually they should go through at least 2-3 heats, they should be at least 2 years of age before they are bred.
BUT you should ONLY breed to improve the breed. Both parents (and preferably further back in the lines) should all have complete health tests to make sure their eyes & joints are stable & ok and have no genetic diseases that may be passed on down the road (like diabetes, allergies, etc... etc...) the parents should also have titles to prove they are a great specimin of the breed.

Can I ask why you want to breed her?
