My question was really directed towards shoulder placement not rib cage
breadth. I agree differences in the rib cage would produce those results I
dont' agree with the connection of "how much" prosternum(posternum) and that
development, but more so, that it is connected to the more forward placement of
the shoulder that we are(at least I am)Â seeing in the breed. In some cases
coupled with an upright or straight shoulder.
And I am currious if judges are actually verifying that.
This area of the standard is a bit ambiguous in that it is not specific how
much extensiont or protusion is optimal for the GSD, my personal
observations(rib cage development aside) would like to see 2 inches as optimal
or preferred.
This same shoulder placement(forward) results in the appearance of "short
necked" dogs. I dont' think we really have dogs with short necks but rather
shoulder placements that make it appear as such.
respectfully,
M

Mike,
Unfortunately, this is a commonly made mistake with the spelling and
pronunciation of this term. Â It is the "Prosternum", not the Posternum...
The prosternum is simply the extension of the sternum or the breast bone.
Together with the ribbing, they provide sufficient room for heart, lungs and
muscle attachment. Â Specifically, a correctly proportioned and placed
prosternum provides for good muscle attachment, which plays a key role in the
movement of fore assembly.
With the prosternum ahead of the shoulder, the muscles act in a forward
direction thus pulling the upper arm to the open position.
Too much prosternum, typically found in conjunction with a breast that is too
wide or over-built, will cause the ulnas to bend outward, making it difficult
to function properly much less, single track.
Too little prosternum typically found with a narrow and under developed chest,
result in the ulnas drawing inward, and the legs drawing out to the French
position. Â Not to mention, insufficient room for the lungs and correct muscle
attachment and usage.
Therefore, no need to check with the hands as it will be visually apparent.
With best regards,
Randy Darnell
