I agree with Judi, as usual. There is also a very wide variance in what constitutes "clear" hips from country to country (if you do a search, there was a recent discussion here, with good links in it - what doesn't pass under some systems passes under others, that sort of thing - it's not enough to have a pass, you have to know which system was used). Many heart problems don't show up in the first couple of years, so IMO (and only in my opinion), a heart clearance before the age of two isn't very meaningful. Eyes have to be recertified regularly (for CERF anyway). I think it's ethical breeding practice to wait until a dog is (mostly) an adult before deciding whether or not to breed it - aside from the health clearances, many dogs don't live up to the promise they had as puppies.

I also see no reason to breed a dog before 2 anyway - that gives you time to put titles on the dog to further confirm that it's a good choice for breeding. There's no rush.
