Breeds commonly known for being black:
* Friesian: These horses are almost always black with abundant feathering (hair around the hooves) and often have white markings.
* Morgan: Morgans can come in various colors, but black is a common color, and many Morgans have feathering on their legs.
* Mustang: Wild Mustangs can be a variety of colors, but black is a common color. They often have feathering due to living in colder climates.
* Tennessee Walking Horse: Tennessee Walkers can be black, and some lines have more feathering than others.
* American Saddlebred: While not typically known for black coats, they can be, and some lines do have feathering.
Important to note:
* Feathering is a trait, not a breed characteristic. It's influenced by genetics and environment, so even within a breed, not all horses will have heavy feathering.
* Color can vary within a breed. While some breeds are known for certain colors, they can come in other colors as well.
* Black is not the only color with feathering. Many horses with bay, brown, or other colors can also have feathering.
To figure out the breed of a specific horse, you need more information than just its color and feathering. Look at its overall conformation, size, and any other distinguishing features. You can also consult breed registries or talk to an experienced horse person.
