If you DO know who is responsible in BOTH pedigrees, for carrying the recessive gene, and you can study future pedigrees to be sure you do not cross either of these dogs with another dog that carries the recessive gene, then you can continue to breed these dogs, just NOT to each other again, or to another dog that also carries the recessive gene. It requires a ton of study and research....it may just be more prudent to spay/neuter both dogs. This is a genetic fault you do not want to pass along to the future lineage of the breed. |
Curious: is there a dna test specifically for this gene? Or has anyone even isolated it? I would guess there aren't a lot of research grants for this when they are still trying to isolate the gene for liver shunt...
If there is no history of a blue born on either side back several generations, spaying/neutering both would be the best solution? I would think it possible that this gene could be carried for many generations without exhibiting itself. I wonder if the (seeming) increase in the number of blue borns is because more people are starting to breed the off colors instead of having them sterilized. Just thinking out loud here...
