Rabbits make wonderful pets, but before bringing one home, many future owners want to know whether they’re getting a male or female bunny. Determining the sex of a young rabbit can be tricky, but with a few simple techniques, you’ll be able to tell if your fuzzy new friend is a boy or girl.

If you’re short on time, here’s a quick answer to your question: The easiest way to gender a rabbit is to lift its tail and look for a round genital opening (female) or a slit-like opening closer to the anus (male). You can also look for dewlaps under the chin which indicate a female rabbit.

In this comprehensive guide, we’ll cover several methods for accurately determining the gender of both baby and adult rabbits, from examining their genital region to looking for key physical characteristics like dewlaps and scent glands.

Check the Genital Region

When determining the gender of a rabbit, one of the first things to do is to examine the genital region. This can provide valuable clues about the rabbit’s gender.

Look for a Circular vs. Slit-Like Opening

The first step is to look at the opening of the rabbit’s genital region. In males, the opening is typically circular in shape, resembling a small dot. In contrast, female rabbits have a slit-like opening that is slightly larger in size.

This difference is due to the presence of the penis in males, which is absent in females. By observing the shape of the opening, you can make a preliminary determination of the rabbit’s gender.

Identify the Anogenital Distance

Another important factor to consider when determining the gender of a rabbit is the anogenital distance. This refers to the distance between the anus and the genital opening. In male rabbits, this distance is typically larger compared to females.

Male rabbits have a longer anogenital distance due to the presence of the scrotum, which houses the testicles. In female rabbits, the anogenital distance is shorter as there is no scrotum or testicles present. By measuring the anogenital distance, you can further confirm the rabbit’s gender.

It is important to note that determining the gender of a rabbit can sometimes be challenging, especially in younger rabbits or those with less visible genital characteristics. In such cases, it may be advisable to seek the assistance of a veterinarian or an experienced rabbit breeder.

Examine Secondary Sex Characteristics

When trying to determine the gender of a rabbit, one of the first things to look for are the secondary sex characteristics. These are physical traits that differ between male and female rabbits and can give you clues about their gender.

Check for Dewlaps

One of the most obvious secondary sex characteristics in female rabbits is the dewlap. A dewlap is a loose fold of skin that hangs down from the chin. Female rabbits tend to have larger and more pronounced dewlaps than males.

If you observe a rabbit with a prominent dewlap, there’s a good chance it’s a female.

However, it’s important to note that not all female rabbits will have a dewlap, especially if they are young or spayed. Therefore, it’s just one factor to consider when trying to determine the gender.

Look for Scent Glands

Another secondary sex characteristic to look for in rabbits is the presence of scent glands. Male rabbits have scent glands located on their chins, which they use to mark their territory. These glands can appear as small, raised bumps or as a slightly darker area on the chin.

Female rabbits, on the other hand, typically do not have prominent scent glands. If you don’t see any glands on the chin, it’s more likely that you’re looking at a female rabbit.

Keep in mind that these secondary sex characteristics are not foolproof methods for determining the gender of a rabbit. In some cases, they may be less pronounced or absent altogether. Therefore, it’s always best to consult a veterinarian or an experienced rabbit breeder for a more accurate determination.

Observe Behavioral Differences

One way to determine the gender of a rabbit is by observing their behavioral differences. Male and female rabbits often display distinct behaviors that can help you identify their gender.

Aggression and Territorial Marking in Males

Male rabbits, also known as bucks, tend to be more aggressive and territorial compared to females. They may display behaviors such as lunging, growling, or biting when they feel their territory is being threatened.

Bucks also have a tendency to mark their territory by spraying urine or leaving scent markings. This behavior is more commonly seen in unneutered male rabbits. If you notice these aggressive and territorial behaviors, it’s likely that you have a male rabbit.

Nesting Behaviors in Females

Female rabbits, also known as does, exhibit nesting behaviors when they are pregnant or preparing to give birth. They may start pulling fur from their body to create a nest for their kits (baby rabbits). This behavior is instinctual and helps provide warmth and comfort for the newborns.

If you see your rabbit pulling out fur and arranging it in a specific area, it’s a good indication that you have a female rabbit. However, it’s important to note that not all female rabbits will exhibit nesting behaviors, especially if they are not pregnant or in a suitable environment for breeding.

Observing these behavioral differences can give you a clue about the gender of your rabbit. However, it’s important to keep in mind that individual rabbits may vary in their behavior, and it’s always best to consult with a veterinarian or an experienced rabbit breeder for a more accurate determination of your rabbit’s gender.

Get Expert Assistance If Needed

While determining the gender of a rabbit may seem simple, it can sometimes be a bit tricky, especially for those who are new to rabbit ownership. If you’re unsure about how to accurately determine the gender of your rabbit, it’s always a good idea to seek expert assistance.

Why seek expert assistance?

There are several reasons why seeking expert assistance is beneficial when trying to determine the gender of a rabbit. Firstly, experts have years of experience and knowledge in handling rabbits, so they are more likely to accurately identify the gender based on physical characteristics.

Additionally, experts may have specialized tools or techniques that can make the process easier and more reliable. They can also provide guidance on how to handle the rabbit safely during the examination, ensuring the well-being of both you and your furry friend.

If you’re unsure where to find expert assistance, consider reaching out to a local veterinarian who has experience with rabbits. They will be able to guide you through the process and provide accurate information about your rabbit’s gender.

Online resources

Another option is to utilize online resources that provide information on rabbit gender determination. However, it’s important to use reliable and trusted sources to ensure the accuracy of the information you receive.

One reputable website for rabbit owners is rabbit.org. They offer a wealth of information on rabbit care, including a section specifically dedicated to determining the gender of rabbits. Their resources are written by experts in the field and can be a valuable tool in your quest to identify your rabbit’s gender.

Remember, if you’re unsure or uncomfortable with attempting to determine the gender of your rabbit on your own, it’s always best to seek professional assistance. This will ensure that the process is done accurately and without causing any harm or stress to your beloved pet.


While sexing young rabbits takes some practice, focusing on the genital area, secondary characteristics, and behaviors will help you accurately determine if your bunny is male or female. Rely on an experienced breeder or veterinarian if you’re still unsure.

Knowing your rabbit’s gender will help you better understand their unique personality and meet their needs as they grow up. With the right approach, you’ll be able to tell whether your new pet is a handsome buck or beautiful doe in no time.
