Should I test breeding dogs, their litters, or both?

Both—we recommend testing your potential breeding pair as well as the litter.

We recommend testing all dams and sires prior to breeding. Our lab can then develop a risk assessment for a litter of puppies from the test results of pairing a specific sire and dam. If the sire and/or dam is a carrier or at risk for a particular condition, we recommend testing the puppies as a portion of them could be at risk or carriers themselves.

The statistical chance of a litter containing carrier or at risk puppies can easily be calculated based on the parents' genotypes.
