The boy's mother is solid black with her dam being black and tan and sire blue/sable
The boy's father is a solid blue (the one that looks black but isn't) his dam blue sable and sire solid blue.
All the rest in the pedigree are either solid black, black and tan or solid blue (not powder but midnight...apparently)
This may not be an unbroken line of black in phenotype, but it is in genotype... let me explain. The A locus is what we are concerned with here and for a dog to be solid black or blue, he needs to be aa, or in the case of dominant black being involved, K. It's another gene (D -dilute) entirely that converts black pigment to blue, so for the purpose of this discussion, those blue dogs are indeed 'black', either recessive aa, or dominant 'black' K.
Would be interesting to know how far back the line of black/blues goes.

Hiya Pod
Thank you for all your information. You certainly know your stuff, way above my head when it comes to this but you have, thankfully, put it into terms that I can at least try to follow.
As to how far back the black/blue goes, I was speaking to his breeder who has his Dam and Sire. Now she is over 70 and took over the line from her Father and he had bred them since a young man, which means that this line goes back to at least the early 20th centuary. She said that they have always had blacks in that line and she is looking out old, old pedigrees for me to get some more detailed information. She claims to remember a solid blue that her Father used for stud when she was but a child and he had 3 generations of unbroken solid blue. (whether this is accurate or not I am not sure, but will wait for the pedigrees) She also claims that the shade of blue was always 'midnight' and never that 'powder' blue and that there were never any 'whites' in the lines. Don't know if that makes a difference.
