Is a black German shepherd with a white chest a full breed?

A black German Shepherd with a white chest can still be considered a purebred if it meets the breed standards set by recognized kennel clubs, like the AKC. However, the presence of white markings is not typical for the breed, which usually has a solid black, tan, or sable coloration. It’s important to verify the dog's lineage and registration to confirm its purebred status. If the dog is registered with a reputable organization, it is likely a purebred despite the unusual coloration.
