can you share any of the credible sources you’ve come across and how the photos were verified to be GSD and not dutch shepherd, akita, sighthound, etc crosses?well, I've been googling and reading and I've come to the conclusion that Brindle German Shepherds are available but the color is considered a fault. They are not common, but if you want one, you can find one. They are not expensive because breeders don't want them. It is recommended they not be bred although they do not seem to carry any more genetic faults than any other German Shepherd. Personally, I think they are funny looking and suggest a PB got loose.
