Grullo is a really beautiful and unique coat color seen in a variety of breeds and types of horses all around the world. Grullo is actually thought to be a form of dun coloring and is classified as one of the shades of dun. This beautiful color is really rare and isn’t often seen in many horses outside of the breeds that can only come in this color.
What Is Grullo?
Grullo is a horse coat color that is relatively rare to see. Mainly seen in certain types of wild horses, grullo is a unique coat color comparable to that of the coat color known as dun. These horses have a sandy-gray coat color with dark legs, a dark nose, a dark mane and tail, and a dorsal stripe. The two most common breeds to have this coloration are the wild breeds known as the Konik and the Tarpan.
How Can I Tell The Difference Between Red/Classic Dun & Grullo?
There are several ways to tell the difference between dun and grullo. The main traits that can tell them apart are:
The main difference between the classic or red shades of dun and grullo horses are the colors of the coats themselves. Dun horses have a yellow-orange tinge to their coats while grullo horses have a dusty sandy-gray color to them. Grullo horses will appear more silver while dun horses look more gold.
Mane & Tail
Dun horses have a mane and tail with a more consistent color. Duns have black manes and tails while grullo horses have black mixed with gray highlights.
Dun horses may have some black on their muzzle and ears, but grullo horses have a lot of it. These horses will often have dark hairs on their nostrils, up to their muzzle, to their face, and on their ears.
What Makes A Horse Grullo?
A horse is considered grullo based entirely on its color and not its breed. A grullo horse has a sandy-gray coat, a dark mane and tail (light streaks and highlights are acceptable), a dorsal stripe, a dark face or muzzle, dark legs, dark ears, and some zebra striping on the legs. Unlike buckskin, a similar horse color, the grullo horse color has no creme gene to affect its coloring.
