Sabling can be heavy, moderate or light. It can appear on the majority of the coat, or it can appear in just a few places.
Just about every sable Pomeranian will have that sabling on his back, also referred to as the saddle. That is a given.
This said, it may or may not appear in other places as well.
When it does appear on other parts of the coat, the sable may be on the head, legs, chest, ruff and/or tail.
It would be exceptionally rare for a Pom to have sable on other areas but not appear on the dog's back; for example being seen on the chest and tail, but not over the saddle.
With this Pom (right, below on mobile), long sable pieces come down over the Pom's back, which are very distinguishable over her light orange and cream, which is a parti coat (two color).
We believe that as a young pup, she most likely had much more sable, but as she grew that sable came out, leaving just these nice long pieces that pleasantly frame her and complements her beautiful dark eyes.
