Why is My Rabbit Bleeding? 7 Causes of Blood Loss in Pet Rabbits

Blood. For rabbit owners, the sight of this vital fluid outside the body is distressing and alarming. A few drops of blood in your rabbit’s cage can spiral worries of serious illness and potential loss of your beloved companion. But before panic sets in, take a breath. Many causes of bleeding in rabbits are treatable with proper veterinary care. By understanding the most common types of hemorrhaging in rabbits, you can respond appropriately when that dreaded red fluid appears. This guide will explore the typical sources of blood loss in pet bunnies, the usual treatments, and key steps for prevention. Arm yourself with knowledge before an emergency strikes. Then act swiftly but calmly when your rabbit needs you most.

Causes of Blood Loss in Rabbits

Blood loss or hemorrhaging in rabbits can occur for a variety of reasons. Some of the most common causes include:

  • Hematuria – Blood in the urine
  • Epistaxis – Bleeding from the nose
  • Melena – Black, tarry stools indicating gastrointestinal bleeding
  • Bleeding from the nail – Often due to trauma or infection
  • Viral Haemorrhagic Disease – A highly contagious and often fatal viral infection in rabbits
  • Bleeding from the anus – Indicative of gastrointestinal issues or trauma
  • Bleeding after neutering – Minor bleeding can occur after this routine surgery

Rabbits have a strong fight or flight instinct. This means they are prone to nose bleeds, bloody urine, and other signs of blood loss when frightened or stressed. Their blood clotting mechanisms are also not as efficient as other mammals. Even a small cut or wound can cause significant blood loss in a rabbit.

It's important to monitor your rabbit closely and be aware of any signs of bleeding or hemorrhaging. Blood in the urine, bloody stools, nosebleeds, and bleeding from wounds should never be ignored. Prompt veterinary care is essential.

With treatment, many causes of blood loss in rabbits can be managed. However, some underlying conditions may be chronic or difficult to resolve. Being alert to signs of bleeding and seeking veterinary advice quickly gives your rabbit the best chance of recovery.


Hematuria refers to the presence of blood in a rabbit's urine. There are several potential causes:

  • Bladder or kidney stones – Gritty mineral deposits that cause irritation and bleeding.
  • Bladder inflammation or infection (cystitis)
  • Kidney inflammation or infection (pyelonephritis)
  • Uterine cancer in unsprayed female rabbits
  • Trauma to the bladder, ureters or kidneys
  • Certain toxins or medications

In many cases, hematuria resolves once the underlying condition is treated. However, it can be a sign of serious issues that need veterinary attention.

Rabbits may pass urine that is pink, red or brown in color. You may see blood drips or streaks in the litter tray. Sometimes blood clots are passed. Heavy blood loss can cause lethargy, poor appetite and dehydration.

Diagnosis involves laboratory urine tests, blood tests, x-rays or ultrasound of the abdomen. Bladder stone surgery may be needed. Antibiotics treat UTIs. Cancer may require spaying or chemotherapy. Kidney disease can be managed long term.

To prevent hematuria, feed a balanced diet low in calcium, offer lots of water, and avoid obesity. Seek prompt vet care for signs of UTI. Schedule regular checkups to monitor for stones, cancer and kidney issues in older rabbits.

While hematuria can be alarming, the outlook for rabbits is often good with proper treatment. Be vigilant for signs of blood in urine and schedule a vet visit at the first indication. Prompt therapy helps resolve the underlying cause and prevent ongoing blood loss.


Epistaxis refers to bleeding from the nose and is a common disorder seen in pet rabbits. The severity can range from a few drops of blood to heavy, life-threatening hemorrhage.

Causes of epistaxis in rabbits include:

  • Trauma to the nose or face
  • Foreign objects lodged in nasal passages
  • Nasal polyps or tumors
  • Dental disease
  • Upper respiratory infection
  • Blood clotting disorders
  • Systemic illnesses like cancer
  • Medications like antibiotics or NSAIDs
  • Dry nasal passages

Stress is also a major trigger for nose bleeds in rabbits. Anything causing fear or anxiety can lead to elevated blood pressure and ruptured nasal capillaries.

Epistaxis is diagnosed based on visible bleeding from one or both nostrils. Your vet will search for an underlying cause like facial trauma, tooth root abscesses, or nasal mass. Blood clotting tests and x-rays may be recommended.

Mild bleeding often resolves with care at home. Reduce stress and limit activity to encourage clotting. Apply an ice pack wrapped in cloth to the nose bridge. Provide hydration and nutrition support.

Severe bleeding requires emergency vet care. Medications to control blood pressure, clotting and reduce swelling may be given. The nose may be packed with gauze to apply pressure. Surgery is sometimes needed to stop hemorrhage and remove polyps.

With treatment, prognosis is fair to good in most cases. Preventing future episodes involves addressing predisposing factors like dental disease, respiratory infections and chronic stress. Regular vet dental care and a calm environment are recommended.


Melena refers to the passage of black, tarry stools in rabbits and is a sign of bleeding in the upper gastrointestinal tract. Potential sources include:

  • Stomach ulcers
  • Intestinal inflammation
  • Ingestion of foreign material or toxins
  • Parasites like coccidia
  • Cancer in the stomach or small intestine
  • Abscesses or perforations along the GI tract

Melena usually arises from slow bleeding that allows time for digestion and breakdown of blood as it passes through the intestines. It causes the stools to appear abnormally dark or black with a sticky consistency.

Other signs that may accompany melena include reduced appetite, lethargy, weight loss, vomiting, diarrhea, and dehydration. Severe blood loss can lead to pale gums, rapid heart rate, and collapse.

Diagnostic tests like blood work, x-rays, ultrasound, and endoscopy can pinpoint the site and cause of GI bleeding. Treatment depends on the underlying condition but may include surgery, medications, fluid therapy, and supportive care.

Preventing melena involves feeding a high quality diet, minimizing stress, and avoiding ingestion of toxic plants or substances. Annual vet exams allow early detection of conditions like cancer that could cause occult gastrointestinal bleeding.

Though melena can indicate serious illness, timely veterinary treatment often results in a good prognosis for rabbits. Pay close attention to stool consistency and contact your vet at the first sign of melena.

Bleeding From The Nail

Rabbits can sometimes bleed from the nail, most often due to trauma, infection or improperly trimmed nails. Signs include:

  • Visible bleeding from the nail
  • Nail appears broken or torn
  • Presence of a wound at the nail base
  • Swelling, redness, and discharge around nail
  • Rabbit seems painful if nail is touched

Trauma from cage wires or sharp objects can tear the nail or cause bleeding under the nail. Bacterial or fungal nail infections also erode the nail bed and surrounding tissue.

Improper nail trimming too short leaves the quick exposed, allowing bleeding from this sensitive blood vessel. Ingrown nails curl into the paw pad causing pain, infection and bleeding.

Treatment depends on the cause but may involve bandaging, antibiotics, antifungal medication, and pain control. Damaged nails may need to be trimmed back further or even removed surgically.

Prevention includes keeping cage wires covered, avoiding sharp objects underfoot, properly disinfecting clippers, and taking care not to trim nails too short. Schedule regular vet checkups to monitor nail health.

While any nail bleeding warrants close monitoring, most cases resolve well with prompt first aid and medical care. Keep your rabbit's nails trimmed at a proper length and seek vet advice at the first sign of trouble.

Viral Haemorrhagic Disease

Viral hemorrhagic disease (VHD) is a highly infectious and often fatal viral condition affecting rabbits. It's characterized by sudden onset of bleeding and very high mortality rates.

Causes and transmission:

  • Caused by caliciviruses that exist in 2 strains – VHD1 and VHD2
  • Highly contagious. Spread via direct contact, exposure to contaminated materials, or infected insects
  • Affects domestic and wild rabbits of all ages

Signs and symptoms:

  • Sudden death
  • Bleeding from nose and mouth
  • Bloody urine or stools
  • Pale gums and lips
  • Fever, loss of appetite, lethargy, trouble breathing
  • Neurological signs like incoordination, paralysis, head tilt, circling
  • Abortions in pregnant rabbits

Diagnosis is made based on clinical signs and lab tests of blood and tissue samples. Supportive care like fluids can be tried, but most cases are fatal. There is no successful treatment. Strict biosecurity and prompt euthanasia of infected rabbits is key to limiting spread.

Prevention involves vaccination, good sanitation, pest control, and quarantine of new rabbits. VHD is a reportable disease and subject to legal restrictions. Outbreaks require cooperation with state veterinary authorities.

VHD remains a serious threat for pet, farmed and wild rabbits. But prompt action and biosecurity can limit its impact. Contact your vet about vaccinating your rabbit and follow strict preventive steps to protect your bunny from this deadly viral disease.

Bleeding from the Anus

Anal bleeding in rabbits has several potential causes:

  • Diarrhea – Excessive straining causes tears
  • Constipation – Hard stools damage rectum
  • GI parasites like coccidia – Irritate lining of colon
  • Rectal ulceration or polyps – Bleed easily when strained
  • Anal gland impaction – Rupture and bleed
  • Trauma from toys or sharp objects – Cuts and tears
  • Sore hocks – Pressure wounds ooze
  • Cancer or other anal tumors – Erode tissues

Bleeding is typically bright red and found near stool samples. The amount ranges from a few drops to heavier bleeding. Look for blood streaks or clots.

Examining the area around the anus helps identify the source. Your vet can perform laboratory tests on stool samples and may recommend imaging or endoscopy.

Treatment depends on the cause but may include parasite medication, dietary changes, antibiotics, surgery to remove tumors, fluid therapy, and pain control. Reduce straining during bowel movements.

Prevent anal bleeding by feeding plenty of hay, hydrating vegetables, and limiting stress. Keep the litter box clean and avoid hard, abrasive bedding. Schedule regular vet exams to check for parasitic infections or other problems.

Though alarming, minor anal bleeding often resolves quickly with treatment. See your vet promptly at the first sign of blood to identify the underlying trigger.

Bleeding After Neutering

Neutering or spaying rabbits is a routine surgery, but a small amount of postoperative bleeding is common. Causes include:

  • Oozing from the incision site
  • Sutures loosening
  • Activity too soon after surgery
  • Lack of restrictive e-collar
  • Clotting disorders
  • Infection

Signs of problematic bleeding include:

  • Visible blood or bloody discharge from incision
  • Swelling under incision
  • Licking, rubbing, or scratching at incision excessively
  • Bruising around surgical site
  • Weakness, lethargy due to blood loss

Prevent excessive postoperative bleeding by restricting activity per vet instructions. Ensure your rabbit wears an e-collar at all times until healing occurs. Monitor the incision site closely.

Contact your vet immediately if you notice excessive bleeding, swelling, discharge, or other signs of complication. Do not remove any bandages or sutures yourself.

With proper surgical technique and postoperative care, most rabbits experience minimal blood loss after being spayed or neutered. Carefully follow your vet’s directions for incision care and activity restriction to support normal healing.
