Gold spot on shoulder?

Do you know for a fact that those are his parents?

Yup. While I have not gotten reissue of his AQHA papers yet, I do have the AQHA issued pedigree.

Though, if you mean, have I spoken to the breeder in person, seen the parents with my own eyes, and verified with the breeder it's the same horse? No. I suppose I certainly could have been lied to.

What colour dun is the mare? Is she red dun or bay dun? Most that are listed as just 'dun' tend to be bay dun. Also, without testing, there is no way to know what agouti genes the sire may or may not carry, since palomino is a red based colour, and agouti only acts on black base.

For what it's worth, to me he looks like a brown horse with a gold spot. I am not sure about the gold spot just appearing, so I will search around and see what I can find. Gold spots are usually that bright palomino colour no matter the ancestry and base colour of the horse, so that isn't what is causing it. I don't think that Stiffler is a 'brownskin' either.

It just says Dun on the papers, but pretty sure the foal picture I have seen of him, his dam was a red dun. I can't seem to find the picture now so I can't be certain.

I think he's just brown, too, I had suspected he wasn't bay because his legs turn brown in his winter coat. I just got to wondering when the color calculator Cori and I looked up didn't show up with that as an option. But he was sold to my friend with a copy of his AQHA 4 gen pedigree and AQHA last recorded owner (who was not the seller) so it isn't out of the question that, to be honest, the information isn't falsified, either. We are still in the process of trying to get a hold of his actual registration papers.

Do you mind if I link this on another forum? It's full of people who are far more expert on colours and genetics than I, and I just can't find any info on Gold Spots developing as a horse ages, all I can find are ones from birth or from first sheds.

ETA: ND I can see you reading this (not a stalker, I swear...) What do you think?

Absolutely, interested to find out more about it. And thanks!

Not sure what to think really. I do think that it is something along the lines of like a bend 'or spot, birdcatcher spot, etc. Not specifically one of those, but something that acts similar in that it can and probably will come and go and not be permanent.

I do know that if his sire is really the palomino and his dam was a red dun like you beleive, there is no way that he is brown/bay.

Chiilaa - care to pm with what forum?

It would be a bit easier if registries would keep up with science *shakes head* How nice would it be if the pedigree said "red dun" or "bay dun" instead of "dun" *mutters darkly*

With a bay dun, they give bay as an option....

Bear in mind that not many colour calculators include brown in their calculations - either because they just don't get it, or they are too stubborn to accept change
