I was going to say the same as k-9mom that there was a brindle in 1922.

10. Brindle B&T
I can't resist mentioning the brindle, which was one of the founding patterns of the breed and seems to have become extinct. The brindling gene affected the tan ground, so that B&T's and bicolours showed a dark striping or marbling (the same effect seen in brindle boxers) over the tan which was not at all unattractive. I wouldn't hazard to guess what a brindle marked sable would look like. Hopefully, if the pattern somehow reappeared, it would not be discarded as atypical.

Eye colour is unrelated to coat pigmentation. A very dark dog can have very light eyes, while a very pale dog can have very dark eyes. The standard says eyes should be as dark as possible, but a dead black eye is rather expressionless. Others suggest the eye should harmonize with the overall colouring, but a lighter face is even more attractive with a rich, medium to dark brown eye, so there is really no reason to settle for a lighter eye. In very melanistic dogs even the gums can be black, and black spotting of the tongue is not uncommon. The skin under areas of black, whatever the pattern, will be an ice blue, but under areas of tan will tend to be pinker. All areas of exposed skin, except for the ear flap and vent, should be black, although in dark dogs, even these can take on a blackish cast. Nails should always be black.

he is a brindle and I know someone with a female pup out of him, been DNA'd and does have AKC papers. the dog has alot of brindling on the legs

I looked the ad up and he is akc, the pup has champion bloodlines and I forget what else the ad said but the one pup is bi color but same striping on the legs I noticed

The dog is B & T.  It is too bad that the brindle was  bred out of the breed.  I like the look in brindle Dutch Shepherds.  I would not pass up a fluke puppy that turned up with brindle, temperament and working ability being what I want, of course.  But, then, I would not pass on a blue that otherwise had the qualities I look for, either. 

Does anyone have his pedigree?

I would like to take a look see

This is full littermate brother of the dog in question, so same pedigree:

Ceph or pod, our dna experts, if I am wrong please correct me:

Brindle is a dominant gene, and always expresses, therefore it was purged  from the GSD, (because it would create less color diversity.)

Every now and then someone shows us brindle markings in the "tan/red" areas of the GSD.

Could this be mutation? A throwback?

Look at the Kieger mustangs for an example of a type reverting back to its origins.

Thanks for sharing the old pic, interesting.

I don't know about the brindle thing existing, but have seen the Dutch shepherd, which looks really cool. And I heard they are super dogs to work with.
