Hi! I'm assuming she's KC registered and there are no endorsements on her registration?
You're right, she'll need to be hip-scored (that's done after she's 12 months old) and eye-tested (both tests will need to be successfully passed, of course!). Ideally you'll have her scored for elbow dysplacia too. You should also have her assessed by an unbiased (we all think our own dogs are the best!) person who's knowledgeable about the breed - usually the easiest way to do that is to show her a few times. If she does well you'll know she's good enough to breed from. It's worth remembering that only about 10% of pedigree dogs are suitable for breeding.
It's at shows that you'll see which dogs are likely to be suitable studs for her. They will also have good hip-scores and clear eye certificates. It's generally considered unethical to breed from goldens before they're two years old.
