As we move forward in the preservation of this wonderful animal, the McNab Shepherd Registry will be requiring genetic proof for all dogs prior to their acceptance into the registry.
ALL dogs will be required to have a Wisdom Panel 4.0 and a DNA profiling test from DDC Veterinary regardless of the breeder you purchased them from. As the McNab Shepherd Registry moves forward with DNA testing it has become apparent that the only way to preserve the McNab without further diluting the genetics is to test ALL dogs for several generations to come. While your dog may phenotypical* look like a McNab and you’ve been told it is a McNab, it may very well genotypically** NOT be a McNab.
Since the DNA testing is something that has not occurred in mass prior to the Registry, very few of us know the genetic makeup of our dogs.
* Phenotype: What an organism looks like because of the interaction of its genotype and the environment
** Genotype: The genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits.
