Dun or Buckskin with dorsal stripe?

I can't decide if this horse is a Dun or a Buckskin? He either has a dorsal stripe or countershading down his back.

You can really see the dorsal stripe in this video.

Smutty buckskin perhaps?

If you scroll down on that link you gave, there’s a stallion ad that says he’s a dun.

The stallion ad might say dun but that horse is 100% buckskin. He may have nd1 which is not dun but can give a horse primitive markings - which will be where the dorsal comes from. It is very clearly an nd1 or countershading dorsal not a dun dorsal because it stops at the tailhead rather than continuing through the tail.

The only mountain and moorland (Great British native) breed that has dun is the Highland Pony. Connemaras do not have dun. However they all incorrectly call buckskin "dun".

This is a dun dorsal stripe:

The above horse is a grulla (black dun) but the image clearly displays what I'm talking about in regard to the dorsal stripe continuing through the tail as compared to the OP horse, where the stripe ends at the tailhead. Additionally the horse in the OP has no other clearly visible primitive markings such as shoulder/leg barring, dark bars on the ears, or a mask on the face. He is a sooty buckskin. As sooty is progressive he will gradually darken.

In comparison, a bay-based dun Highland Pony:

Note the darker face and the barring on the legs. This photo isn't ideal to see the dorsal continuing through the tail.

A "dun" Connemara (actually sooty buckskin):

Note the lighter/same colour face and the lack of leg barring.

I have to agree that he's a buckskin as Connemara ponies don't carry the dun gene. His owners may have continued the British and Irish tradition of using 'dun' to describe both buckskin and dun ponies.

As for the other photos, traditionally, black-based dun Highland ponies are described as Mouse Dun and not black dun. Mouse Dun tends to be used for every breed that colour, we never use Grulla/o.

The bay-based dun Highland pony mare is a Yellow Dun. The bonnie little mare is from the Lurgan stud in Perthshire.

@Caledonian I'm familiar with the breed terminology for Highlands. I have a friend who breeds them. However it isn't considered correct in the colour genetics community. The grulla isn't a Highland (google said it was a Sorraia), I just wanted a good picture to demonstrate the difference between a dun dorsal and an nd1 dorsal.
