What breeders still don't get, is please do the genetic testing that is Available for your breed. This testing can be done at days old, usually through a cheek swab.
For Yorkies Pra gene, Hyperuriscosuria, and Color Dilution Alopecia genetic tests.
If you breed clear to clear it is my understanding you will not have a carrier nor a dog affected with these diseases.
And the more genetic tests we have the better. For breeders can find out very early on, if any of their very young pups should be kept for breeding. |
If the large amounts of variation can help the health, that would be ideal, but would that be contingent on the OP's question of whether or not breeding close to the standard would be even more important?
