Duke1965,hiya.my last litter was funnily enough was to a sable male from a black and gold bitch.i had 6 pups by c-section,3 males and 3 females ,all b/g except for 1 sable bitch.1 b/g male and 1 b/g female had their ears up at 5 weeks.all had their ears up by 8 weeks.in fact the purchaser of the l/c b/g male did remark that he,d never seen a gsd puppy have its ears up so early.in fact i,ve had a bitch who had soft ears,1 up but very wavy and the other didnt go up till she was 4 years old and guess wot they were then firm.dogs do tend to amaze us all the time.never did show her.she and her 2 litter mates were just our pets as are all our dogs.Carole.

It could be (I don't know) that the trait for ears is closely located on the chromosome near to the agouti locus for color pattern.  When genes reassort themselves, it's done in sectioned lengths (groups of genes) that tend break in same-marked points on the chromosome, that are then inherited from one parent or other, rather than every single locus independantly.

Here's your pups...






These two pups below  that I produced are the same age, but neither's ears are up yet.  What I noticed at the time, was their ear types were different.  The black's hung more to the side, and the sable's were more foreward.  The mother was a daughter of Nuky (a west/czech mix) and she had very expressive control of her ears, a trait I saw less pronounced in the czech lines in general.  I believe the black pup inherited her ear type.  The sable pup's ears developed more like Faro's, a czech/slovak dog, and more similar to his sable coloring than the gray-sable of his mother's.  So, ears and coat color might* be 'genetically linked'.


 

 

In further possible support of that theory, this male was from a different litter by Faro, and he ended up with his mother's ear type and sable coat type, rather than Faro's.





The mother's ears were very broad, and her coat very soft.

these are also czechlines daryll , I had pups from the father before, a lot of the pups ears were standing  up early , but I never noticed this difference in coulor related to ears
these pups are

I'm not attempting to make a bloodline correlation, but instead a parental correlation.  What I'm infering is, that the sable pups might develop the sable father's ear type, while the blacks develop an ear type more similar to their black mother's.  Because the sire's sable-coat/ear-type is more dominant than his black-coat/ear-type.  Her  black-coat/ear-type might be more dominant that his black-coat/ear-type.  The pups might have similar spurts and overall growth rates and final development characteristics for their respective group.   I'd be interested to know how it turns out.  Judging the pedigree pictures of the parents, they have very distinctively different ears.  Keep in mind, this is just total conjecture on my part.  And it could very well be one of those things that much of the time is true, just not all of the time (like the arm-bar toe-penciling is often associated with a recessive black gene --but never the rule.

I also think this is what happend here
I know of other offspring of the male , but never had pups with this female with another male before
