Rabbit Hemorrhagic Disease: What Rabbit Owners Should Know

Rabbit hemorrhagic disease is a fast-moving viral infection that damages a rabbit’s liver and interferes with normal blood clotting, and it is often fatal. Most owners picture danger as something that prowls the backyard, yet this virus has a talent for slipping past closed doors, and a bunny who nibbled breakfast hay with gusto can be gravely ill by evening. Since 2020, a newer strain known as RHDV2 has surfaced in rabbit communities across the United States, which has moved rabbit hemorrhagic disease from a distant headline to a very real question for Westchester County households. At Veterinary Center for Birds & Exotics in Bedford Hills, NY, our team hears that question more and more from pet rabbit families. The more you understand about rabbit hemorrhagic disease today, the calmer and quicker you can be on the day it matters.

So, What Is Rabbit Hemorrhagic Disease?

Rabbit hemorrhagic disease, often shortened to RHD, is a viral illness caused by a calicivirus that targets rabbits and their wild relatives. Veterinarians rank it among the most serious threats to rabbit health.

One Virus, Two Strains

Researchers describe two main versions. RHDV1, the original strain, mainly strikes adult domestic rabbits. RHDV2 is the newer and more adaptable variant, and it can sicken a broader range of rabbits, including young kits and animals that were vaccinated only against the older strain. The name comes from the way the virus affects the body, since “hemorrhagic” refers to the bleeding problems it can trigger.

Which Animals Are Affected

Pet rabbits of every breed and age can catch the virus. Wild cottontails and certain hares can carry RHDV2 too, which means neighborhood wildlife may play a role in how the virus moves around. People, dogs, and cats cannot contract rabbit hemorrhagic disease, so this is a rabbit-only concern for your household. That also means a multi-pet home does not need to worry about the virus jumping to the family dog or cat, though everyone in the house can still carry it on shoes and clothing.

Why the Virus Is So Hard to Shake

The virus is remarkably tough and can persist on bedding, fur, soil, and other surfaces for a long time. A single case of rabbit hemorrhagic disease can therefore ripple through a community of rabbits well beyond the first victim. Animal health agencies track confirmed cases, and veterinarians often help report suspected ones. If you ever worry about your rabbit, phone the clinic before you head in so our staff can prepare for your arrival.

What Do Rabbit Hemorrhagic Disease Symptoms Look Like?

Rabbit hemorrhagic disease symptoms range from barely noticeable to dramatic, and sometimes they never appear at all. That unpredictability is a big part of why owners find this illness so unnerving.

When There Is No Warning

The most heartbreaking presentation is a rabbit found gone with no earlier sign of trouble. Because the virus can act so swiftly, many owners never get the chance to watch a decline unfold, and that reality says nothing about the quality of their care.

Subtle Changes That Deserve Attention

When rabbits do show signs, they typically appear within days of exposure. Rabbits instinctively hide illness, so small shifts in behavior carry big weight. Owners have reported changes like these:

• A rabbit sitting hunched in a corner, tucked away from the usual household action
• Rapid or labored breathing while at rest
• Bleeding from the nose, mouth, or back end
• A yellow tint to the gums or skin
• Seizures, paddling legs, or a sudden loss of coordination

Why Appetite Changes Always Count

Many early signs resemble other rabbit ailments, including digestive upset, so they are easy to dismiss at first. A rabbit that stops eating is always an emergency, whatever the cause. Because rabbit hemorrhagic disease can progress within hours, a quiet evening can turn urgent by morning.

Who to Call and What to Skip

Call your veterinarian right away and describe what you see. Please skip any home treatment attempts, and avoid waiting to see whether things improve overnight. Our team at Veterinary Center for Birds & Exotics can explain the safest way to bring your rabbit in so that other rabbits stay protected.

How Does Rabbit Hemorrhagic Disease Move Between Rabbits?

Rabbit hemorrhagic disease spreads through direct contact between rabbits and through anything that carries the virus from place to place. Even rabbits who never leave the living room are not automatically in the clear.

Nose-to-Nose and Beyond

Infected rabbits shed the virus in saliva, urine, and feces. A healthy rabbit may pick it up by sharing a sniff with a sick companion or by touching anything those secretions have reached. Rabbits that have died from the illness can remain a source of virus as well, which is one reason wildlife encounters concern veterinarians so much. Even a brief meeting at a fence line can matter when rabbit hemorrhagic disease is circulating nearby.

Hitchhikers on Everyday Objects

The virus is happy to catch a ride. These are some of the surprising carriers veterinary teams discuss with owners:

• Shoes that crossed a park lawn or a yard with wild rabbit activity
• Fresh hay, greens, or clover gathered from outdoor spots
• Carriers, water bottles, and bedding borrowed from another rabbit home
• Flies and other insects that travel between animals
• Hands and sleeves after petting a rabbit at a show or rescue

When Home Is Not a Fortress

Indoor living lowers some risks but does not erase them. Rabbit owners can ask their veterinarian how their own routines, such as boarding stays, rabbit events, and foster visits, shape their household’s exposure. Following county news about rabbit hemorrhagic disease cases also helps you adjust as local risk changes.

Can You Protect a Pet Rabbit From Rabbit Hemorrhagic Disease?

Yes, rabbit owners have a powerful tool against rabbit hemorrhagic disease, and that tool is vaccination. Preventive care is also far safer for your rabbit than any scramble once illness has started.

The RHDV2 Vaccine Conversation

A vaccine against RHDV2 is available in the United States, and veterinarians can obtain it for their rabbit patients. Schedules typically include an initial dose, a booster, and periodic updates, with your veterinarian setting the timeline that suits your rabbit. Since older vaccines were built for earlier strains, ask specifically about RHDV2 coverage. Even indoor rabbits are worth discussing, because the virus is so deadly and so difficult to avoid completely.

Questions Worth Bringing to Your Next Visit

Preparing a few questions turns a routine wellness exam into a plan. Consider asking:

• Is my rabbit’s vaccine record current for the RHDV2 strain?
• How should I handle a new rescue rabbit before it meets my current one?
• What precautions make sense if I volunteer at a shelter or attend a rabbit show?
• Which sources of hay and greens carry the least risk?

Why Rabbit-Savvy Care Makes a Difference

Rabbits are exotic companions with needs that differ from those of dogs and cats. A practice experienced in rabbit medicine can recommend the right vaccine, explain what is happening in the region, and act quickly if an outbreak is reported nearby. Our clinic follows current guidance and stays connected with state animal health officials. That awareness helps us give Westchester rabbit owners practical, up-to-date answers instead of guesses.

A Short Conversation Now Can Matter a Great Deal Later

Rabbit owners have a real chance to stay a step ahead of this virus, and two simple actions make that possible. Neither one takes long, and both can start with a single phone call. If your rabbit has never received an RHDV2 vaccine, or you cannot remember whether the last one was recent, call Veterinary Center for Birds & Exotics in Bedford Hills, NY, at (914) 864-1414 and ask us to look at the record. We are glad to talk through your rabbit’s situation and answer any questions about rabbit hemorrhagic disease. 

Your instincts matter. If your rabbit stops eating, seems unusually tired, or shows any sign of bleeding, reach out right away. You know your rabbit better than anyone, and our team is ready to help the moment you notice a change.
