A grulla horse is a unique and striking equine known for its distinctive coat color, which is a smoky or mouse-gray shade with a black mane, tail, and lower legs. This coloration is the result of the dun gene acting on a black base coat, creating a beautiful and rare appearance that is highly sought after by horse enthusiasts.
What Makes a Grulla Horse Unique?
The grulla horse stands out due to its uncommon coat color and specific genetic makeup. Unlike other horses, grullas have a slate-gray body with primitive markings such as a dorsal stripe, zebra-like stripes on the legs, and often a shoulder stripe. These markings are the result of the dun gene, which modifies the base coat color.
