Thats true, I guesss I could get my carrier retested now. Not sure there is a reason to retest the clear as the parents were clear and carrier.
Yes there is a reason to retest clears, if you read Dr Johnson's write up from the Nationals, he clearly says that even pClear to pClear could produce Carriers, so a pClear to pCarrier could make that pup a Carrier or even Affected if that pClear turned out to be a Carrier.
It is recommended that all potential breeding stock be retested with the direct test. And if I had a pClear to pCarrier regardless if I were considering breeding, I would retest.
