Have you looked at Celhaus? Celhaus German Shepherds Sheridan Wyoming
I spoke to her about a pup for myself years ago when I was living in Oregon. I opted to go with a breeder in Oregon. Other than speaking with her I have no personal experience with her. I also ran into several of her dogs competing in agility and obedience. It appears she now has mostly sables tho.
If you want to go as far as Idaho check out Theishof German Shepherd Puppies for sale in Boise, Idaho.* We can ship to any state!
She is in Boise. Again, no personal experience but I have seen her dogs competing.
Another in Idaho that I do know. Guardyan Kennels - Home
And finally - Vom Haus Vianden
I know several of her dogs nad have competed against her myself.
Those may be too far for you it is a start anyway.
