Dog Gene Puddles. Now.

To me, it seems that in dog breeding, "pure" has come to mean: "We don't mix our dogs with dogs not related to them".

Incest is NOT best, the gene puddles must flow back into each other, but the current system fights that, and only a few breeders will to swim against the stream of conformity even try at hybrid dog breeding.

The result is inbred and often deformed, and seriously unhealthy dogs, and dogs with unfit temperaments.
