I bought a bitch at 20 months old from another kennel. She had an accidental breeding at 12 months. I did her OFA hips which came out excellent, showed her a bit and didn't breed her until about 3 years old. She had 2 or 3 other litters with me, never an issue. Her grandchildren are currently with me :). She died of Cancer at 8 years old :(, but never an issue due to the early breeding. Just be sure to feed her well and give her a nice long break before she's bred again.
