She says:

One last comment. The GSD is a working breed, perhaps the very best. While there is nothing wrong with a dog serving as a family pet, this is not its primary function. Breeding GSDs to accommodate the minimal demands of suburban life is like manufacturing a BMW with the engine of a sewing machine. It will certainly look good and give its owner's ego a boost, but the essence is gone. If a pet owner is not willing to provide the training and exercise this breed requires, there are many other breeds, including several listed here, which would be more appropriate. If you cannot cope with a working breed, please do not buy a German Shepherd Dog. Breeders who are unwilling to promote their dogs' working capacities should also find another breed to produce. Breeding away the working ability of a GSD is like wiping the smile off the Mona Lisa - the beauty is still there, but the greatness is gone.

 

 NNnnnNow, I assume you must have read this, since you posted the link on your site. Knowing this, how can you possibly justify what you do?

Also, the end of the video you posted has that famous quote from the GSD breed founder, Max von Stephanitz:

"Take this trouble for me. Make sure my Shepherd Dog remains a Working Dog, for I have struggled all my life long for that aim." 

 

Again, how can you justify breeding GSDs just for pets?
