Dun Brindle (B+b/B+B+);

A mutation of brindle that always expresses with white barring on their legs, moving up the body in a spotty/stripe pattern. Horses with Dun Brindle always have white tipped ears or even fully white ears as well as a white mane and tail.
Horses with a single allele (B+b) show with more minimal expression (image one); more spots than stripes.
Horses with both alleles (B+B+) show more extensive expression; less spots with thicker stripes. They also tend to have socks on all four feet and a white belly that leads into the striping around the barrel.
