That is quite a gene pool you two have.
The only way to enlarge the gene pool is to bring in new bloodlines from the wild.
Those of us who do launch ourselves into the bigger gene pool soon reap the benefits and become much better fencers.
I'll be glad to see the gene pool extending.
German Shepherds have become a popular breed, and as with many breeds before them, indiscriminent breeding by those seeking a quick cash return has resulted in lesser quality animals contributing to the gene pool.
