Goat Horns: 10 Things You Should Know

When you look at goat horns, you may be assuming they’re just hollow appendages or dead bones. After all, horns can’t be that complicated, right? Wrong! These are living, sensitive growths that serve a variety of purposes, from communication to defense and social dominance. Sometimes, goats even use them to give their humans an affectionate headbutt. Read on to discover 10 things you should know about goat horns.

1. Not All Goats Have Horns

It might come as a surprise to find that not all goats have horns. Of course, some goats do, but others are naturally born without them. Breeders call these “polled” or “naturally polled” goats, which are similar in every other way to horned goats; they just don’t have horns. Also, contrary to popular belief, both male and female goats can have horns. When they do have them, female goats typically have smaller horns than males. However, the difference isn’t always much, so if goats of different sexes are not standing side-by-side, then observers might have a difficult time telling them apart just by this feature.

Fortunately, there are other ways to differentiate between male and female goats. The most reliable method is to look under the tail. Male goats will have a single hole under their tails, which is the anus. Females will have two holes: one for the anus and one for the vagina. Another method is to look for the scrotum on intact males or the udder on females. Additionally, male goats give off a strong, musky odor from their sex glands during mating season.

2. Goat Horns Are Made of Bone and Keratin

Goat horns are incredibly strong, and with good reason. The core is made of thick, live bone growing from the goat’s skull. This bone is covered by a layer of keratin. Keratin is a vital component in hair, fingernails, hooves, and claws. This combination allows the goat to use its horns to vigorously butt and jab.

The horn’s outer layer is mostly insensitive to pain. However, the bone underneath houses blood vessels, tissue, and nerves. Any damage to the horn will cause pain, and attempts to remove the horn completely can be agonizing for the goat.

3. Goat Horns Never Stop Growing

That’s right, goat horns continue to grow as long as the goat is alive. It’s even possible to tell a goat’s age by counting the annual growth rings on its horns. As the goat ages, horn growth slows lengthwise, and the horn begins to grow thicker and stronger around its base.

Despite this continual growth, horns won’t usually grow back if they break off. If the horn is broken off the skull, it may even expose the sinus cavity, and if this happens, then the goat will need immediate veterinary attention.

4. Horns Are Recessive

As we mentioned earlier, some goats have horns and others don’t. However, their horns are actually the result of recessive genes. The gene for polled goats (goats without horns) is dominant. This means that a goat only needs to possess one polled gene to be born without horns. Conversely, as the horned gene is recessive, a goat must possess two of these genes in order to be born with horns. Therefore, if a goat inherits one polled gene (P) and one horned gene (p) then it will not have horns as the polled gene is dominant over the horned gene (Pp).

5. Goat Horns Help Regulate Body Temperature

Strangely enough, goat horns actually help regulate a goat’s body temperature. Goat horns can aid in thermoregulation to some extent by dissipating heat. The blood vessels in the horns carry blood from the body close to the keratin sheath, where it loses heat. Then the cooled blood returns to the body. It’s nature’s all-natural air conditioning for goats. Without this process, they struggle to stay cool.

For this reason, some goat breeds should never be dehorned. The Angora goat, which has a thick, luxuriant coat, is one such type. They have no other way to keep cool in hot weather and may easily perish from overheating. Goats that live in hot climates are particularly susceptible to this happening.

6. Goats Use Their Horns to Communicate

Goats are lively, playful, social creatures capable of feeling and expressing emotion. In addition to their voices and facial expressions, goats also communicate their state of mind with their horns. Headbutting is a common behavior that can have a variety of meanings. Goats may headbutt humans or each other to express affection. It may also be an invitation to play.

However, sometimes a headbutt carries a more serious message. Goats maintain a strict social hierarchy among themselves, enforcing it with their horns. Though goats don’t often impale each other, they may push and butt to indicate dominance. Stronger males may bully weaker males into submission.

7. Many Domestic Goats Are Dehorned

Removing a goat’s horns usually occurs in one of two scenarios. The first is shortly after birth. The process of disbudding involves preventing a kid’s horn tissue from developing into nubs and eventually into full-blown horns. To ensure they do not spout, disbudding typically takes place no later than three weeks after birth. Practitioners cauterize the horn tissue either with hot irons or, less frequently, with caustic paste.

The second scenario involves removing an adult goat’s fully-formed horns. This is the process of dehorning, or cutting off the horns in their entirety. The procedure is extremely risky, more so than disbudding, and can be painful. However, both procedures are controversial.

Livestock owners typically choose to practice disbudding and dehorning to prevent goats from causing injuries to themselves or others. It also minimizes the risk of property damage.

8. Baby Goats Are Born Hornless

Thankfully for mother goats, all baby goats are born hornless. Instead, they have horn tissue that, over time, becomes attached to the skull and forms nubs. It takes about three weeks for these nubs to appear. Baby goats learn to use their horns by playing with other kids and watching their mothers.

9. Goat Horns Come in Different Shapes

Goat horns come in a couple of different shapes, including straight, curved, and corkscrew. The bulky Markhor goat features majestic corkscrews. Nubian goat horns, on the other hand, are elegantly curved. Other goat species and breeds have simpler, straighter appendages, though even these may have a slight curl to them.

10. Goats Don’t Shed Their Horns

Many antlered species like deer, moose, and caribou shed their antlers seasonally. However, for goats, these are permanent fixtures. If disbudding, dehorning, or breakage doesn’t occur, the horns will remain firmly rooted to the skull. They will never shed and grow back.

Goats make loveable pets and useful, productive livestock. You may even find yourself on the receiving end of a friendly headbutt. Just make sure to watch out for those horns!

Bonus: What Are the Different Types of Goat Horns?

There are generally eight different types of goat horns. Below is a list of each with a bit of interesting info about each.

• Straight Horns — Varied thicknesses or lengths can be seen in these straight horns, displayed in goat breeds like the pygmy goat.
• Spiral Horns — These elegant horns have tight spirals or curls with pointed tips. Species like the Siberian ibex sport spiral horns.
• Twisted Horns — An irregular twisted or spiral shape with varying degrees of thickness, based on breed, characterizes this horn. You’ll see twisted horns on Nubian goats.
• Corkscrew Horns — These horns resemble a corkscrew you’d use to pop open a wine bottle and can vary from short to elongated. A good example of this horn shape can be seen on Pakistani markhor goats.
• Sickle-Shaped Horns — Resembling the shape of a sickle, these horns curve backward, then forward, with varying curvatures and lengths. Check out Boer goats for an example.
• Semi-Curved Horns — Saanen goats have semi-curved horns, which are smooth and have a moderate curve pointing upward or slightly backward.
• Hooked Horns — Think of a fishhook for an idea of this type of horn shape, seen in a Chamois goat-antelope.
• Upward-Curved Horns — These non-spiral horns curve upward and can be seen in Nigerian dwarf goats.

CORRECTION: This article was updated on March 3, 2026. A previous version of this article misstated that the Siberian ibex (Capra sibirica) and markhor goat (Capra falconeri) are goat breeds when, in fact, they are different species. The domesticated goat, Capra hircus, has approximately 300 different goat breeds, such as the Anglo-Nubian and the Boer.
