Lucky remember the Petfinder link I sent you?
I'd encourage you to visit your shelters, get to know some of these dogs.
The German Shepherd, like many overbred dogs out there, is in bad shape, genetically speaking.
You should only be breeding the "best of the best", health wise and temperament wise.
We have an awesome dog, temperament wise. But his elbows are shot and he's barely over a year of age. He won't live beyond 3-4 yrs. at this rate. That's from people breeding without knowing the genetics behind the dogs they have.
It's critical you learn more about this and find out how to become a responsible breeder, and stop breeding dogs without history (titles/pedigrees) behind them.
That's all I can say...and the best I can say it.
It is a free country. You can do whatever you want (other than break laws
But for the love of the breed, please be responsible with your dogs.
