sheep with horns

Lambs never have horns, but some breeds of adult sheep do. Although mostly male sheep have horns, there are varieties where the females also have them. Today we’ll take a look at which sheep have horns and why!

When we think of sheep, most of us think of domesticated sheep raised for food and clothing. However, did you know there are over 1,000 different breeds of sheep throughout the world? Sheep range from domesticated farm sheep to the wild sheep many of us have seen roaming the mountains regions of Northern America.

If you live and work in a city or town, you probably only ever see sheep occasionally and from a distance. Fluffy dots on the hillside, with white cotton bodies and bobbing heads. It would be easy to assume from a distance that sheep don’t have horns, but some do!

Because of the number of sheep breeds available, it can be confusing as to whether or not sheep have horns. The truth is that some species of sheep do have horns while others do not. There are a few factors that contribute to whether or not sheep have horns, including genetics, breed and gender.

What Are Sheep?

Sheep are four-legged mammals that often have thick, wooly coats. Not all sheep are domesticated, but the sheep we commonly think of when asking do sheep have horns are the domesticated sheep in the genus Ovis.

Evidence shows that these species of sheep have been domesticated since at least 5,000 BC. It is believed that these animals were originally domesticated from a wild species of sheep and used early on for much of the same purposes as they are used for today.

Sheep Vary A Lot

Different sheep species can range in size, weight, and appearance. They often stand around 46 inches in height and can weigh between 80 and 400 pounds depending on the species. Most sheep have a decent lifespan of between 10 and 12 years both in the wild and in captivity.

Due to their behaviors and many common misconceptions, it’s often thought that sheep are unintelligent. The truth is actually quite the opposite! In fact, sheep are highly intelligent animals and can solve problems and build emotional bonds with one another. They are even capable of communicating different emotions to one another using unique vocalizations. Who knew!? Another interesting fact about sheep is that while many of them have horns, not all of them do. So, why do some sheep have horns while others don’t?

Do Sheep Have Horns?

Many sheep do have hollow horns that grow in a curling motion out of the top of their head. For most species of sheep, it is typically the male that grows horns, though some female sheep in other groups or breeds can also grow horns.

Sheep horns are made of the same material as our fingernails are made of, and sheep use their horns as tools to help them eat or even fight if they need to. Male sheep often grow longer horns than females and, depending on the species, some sheep can grow horns that are over three feet in length.

Although a sheep’s horns can continue to grow throughout the sheep’s lifetime, they typically don’t appear until later in the first year of a sheep’s life. Once they emerge, sheep horns will grow rapidly between the first and third year of a young sheep’s adolescence.

Of course, not all sheep grow horns. But why do some sheep have horns while others do not? The factors that determine whether or not a sheep will develop horns include genetics, gender and breed.

Horned Sheep Breeds

Sheep breeds with horns include:

  • Bighorn sheep
  • Thinhorn sheep
  • Jacob sheep
  • Mouflon
  • Arabi rams
  • Racka sheep
  • Arapawa sheep
  • Wiltshire Horned sheep
  • Gute sheep

Lamb Horns

If you have dogs, you have likely heard of lamb horns. These chews are not bone and, as we mentioned above, are instead made of the same thing as our fingernails are. This substance is called Keratin.

Though these horns are called lamb horns, they are not necessarily from lambs. As we mentioned above, lambs (AKA immature sheep), don’t develop horns until they reach early adulthood. This typically takes place in the first year of their life. Sheep typically take about six months to mature fully, and sheep under the age of six months are considered lambs. During this time, they will likely not have fully developed horns.

Long Horn Sheep

Long horn sheep, also known as bighorn sheep, are some of the most popular wild sheep found throughout the United States. Some of the traits that make these sheep so famous are their unique horns. Bighorn sheep are common throughout North America and typically live in our mountainous regions where they are known for scaling steep rock faces and cliffs.

Large, muscular, and agile, big horned sheep are not the average domesticated wooly sheep you may be familiar with. In fact, they are much larger than domesticated sheep and full-grown males often weigh closer to 300 pounds.

When asking do sheep have horns, we should note that both female and male big horned sheep have horns. Males can have much larger horns that grow in a half-circle shape. Because these horns continue to grow throughout the male’s life, the horns can continue to curl around his head.

Female big horned sheep also have horns, though they are often much smaller and less circular. Big horned sheep are wild sheep that are generally a beloved sight four tourists. The distinctive big horned sheep are also commonly hunted for their meat and their horns. And big horned sheep horns are sometimes used as ornaments or for religious ceremonies.

Ewe Horns

Male sheep are often called rams while female sheep are often called Ewes. Female sheep or ewes can grow horns, though they are less likely to grow horns than their male counterparts.

Female horns tend to be smaller than male horns, though different species of sheep can grow larger horns. Genetics can also play a large role in the ewe horn size, as we have mentioned. Like all sheep horns, ewe horns are hollow and made of keratin.

Sheep And Horns

Some sheep have horns, but not all of them. There are over 1,000 different species of sheep throughout the world and not all sheep are capable of growing horns. On the flip side, some sheep not only do grow horns, but they can grow multiple horns on their head.

Horns are not the same thing as antlers. In fact, antlers are made of bone while horns are made of keratin. Animals that grow antlers include moose, caribou, elk and deer. Antlers are also an extension of an animal’s head, which makes it even more interesting that antlers are commonly shed throughout the year.

Horns, on the other hand, are not shed and can continue to grow for the entirety of the animal’s life. Along with sheep, other animals that can grow horns include bison, Rhinoceros, Antelope and more.
