In theory, puppies after clear parents are also clear, but there is always very low, but not nonexistent, probability of spontaneous mutation in the gene. Bad thing is, this mutation would probably not be recognized by the test. But this is true for any genetic illness. And the probability is so low that it can be ignored for most purposes (unless dwarves start to be born after clear parents).
In my opinion, to get a certificate, the pups should either be tested for the gene itself, or for the paternity of the proclaimed parents (which might be more economic if the parents have certificates for several genetic disorders - but I am not sure if it would be accepted).
