This young dog (just turned one) is purportedly a purebred Labrador. Born solid chocolate and chocolate at the time of his purchase his striping has come on with age according to his owner. Unfortunately the owner didn't "pay to get his papers" but IS still in contact with the breeder. I hope to get more information on his lineage (for educations sake only, colour fascinates me.) I've seen brindled Labs before, it is a known mismark in the breed...but NOTHING like THIS:
