What is Splenic Hemorrhage?

A splenic hemorrhage is an extremely dangerous situation that can become fatal quickly. The blood from the spleen leaks into the abdomen, causing anemia and shock from loss of blood. If the cause is from an injury, you will most likely know that your dog has internal injuries right away due to the swollen abdomen and sudden weakness or vomiting. However, if your dog has a spontaneous splenic hemorrhage, the most common cause is splenic tumors, which may be either cancerous (malignant) or noncancerous (benign). Both types can cause splenic hemorrhage, hematoma (accumulation of blood in the spleen), and death without treatment.

Splenic hemorrhage (hemoabdomen) is a life-threatening condition not uncommon in large breed dogs such as the German Shepherd, Labrador Retriever, Doberman Pinscher, and Great Dane. A splenic hemorrhage may be spontaneous or traumatic. The most common cause of a spontaneous hemorrhage is neoplasia (80% of the time), which is a tumor in the spleen and the most common cause of traumatic splenic hemorrhage is being hit by a car. That is one of the main reasons why it is so important to keep your dog on a leash when he is outside and not restricted by a fence. Splenic hemorrhage can be fatal in less than an hour if not treated, so if your dog collapses, weak, and has a bloated abdomen, you need to take him to a veterinary emergency hospital.

Symptoms of Splenic Hemorrhage in Dogs

There are two types of splenic hemorrhage but if your dog has either type of splenic hemorrhage, you will likely notice signs such as:

  • Weakness
  • Vomiting
  • Bloated abdomen
  • Difficulty breathing, may be labored or your dog may be gasping for air
  • Pale gums or lips
  • Not eating or drinking
  • Sudden unexpected collapse for no obvious reason
  • Weight loss (if the condition is chronic from slower blood loss)
  • Low blood pressure (extreme lethargy, confusion, dizziness, fainting)
  • Shock (nausea, anxiety, cold limbs, restlessness, collapse)


  • Spontaneous splenic hemorrhage is caused by an underlying condition.
  • Traumatic splenic hemorrhage is caused by an injury to the chest or abdominal area

Diagnosis of Splenic Hemorrhage in Dogs

The veterinarian will do a fast examination while you explain the symptoms you have seen and if your dog has had any injuries or illnesses recently. In addition, the veterinarian will need to perform an abdominocentesis. This procedure is done by inserting a needle into the abdomen to extract a sample for microscopic evaluation. An echocardiogram (ECHO) and electrocardiogram (EKG) should also be done due to the possibility of shock and cardiac arrhythmias.

Additionally, abdominal x-rays, CT scans, an MRI, and an ultrasound are good for determining the amount of free fluid in the abdomen. Abnormal biochemistry results include a decrease in albumin and increased blood glucose, alkaline phosphatase, and alanine aminotransferase. Your dog will also be anemic (low iron) due to blood loss. Also, a coagulation profile will be done, but is normal in many cases. A packed cell volume (PCV) analysis will show a decreased PCV.

Treatment of Splenic Hemorrhage in Dogs

For a serious condition such as splenic hemorrhage, treatment may have already been started during diagnosis. The veterinarian may have started intravenous (IV) fluids, oxygen therapy, and blood transfusions. Other treatments include medication, abdominal wrapping, and possibly surgery.

Intravenous (IV) Fluids

Due to blood loss, intravenous (IV) fluids are essential to recovery. The standard treatment for splenic hemorrhage is isotonic crystalloids until vital signs improve followed by colloid boluses if needed.

Blood Transfusions

The veterinarian will most likely transfuse your dog with fresh whole blood or packed red blood cells to increase the PCV. If coagulopathy is the cause, fresh frozen plasma may be used instead.

Abdominal Wrap

The veterinarian will wrap your dog’s abdomen tightly with a compression bandage, which slows the blood loss while getting further diagnosis if needed.

Oxygen Therapy

If your dog is having a difficult time breathing, oxygen will be provided with a nasal cannula or muzzle mask.


Pain relief is important to reduce stress on your dog, which helps any treatment succeed. Narcotics or NSAIDs may be given until your dog is stable. Steroids may be given to decrease inflammation and also help with pain.


Surgery to remove the spleen is only done if absolutely necessary. If the bleeding cannot be controlled with any of the above treatments, the veterinarian will perform a splenectomy (removal of the spleen). This surgery usually completely solves the problem. However, if the veterinarian finds a malignant tumor, radiation or chemotherapy will have to be done as well.

Recovery of Splenic Hemorrhage in Dogs

Your dog will most likely be kept in the hospital for several days so they can keep him under 24 hour observation while he recovers from surgery. Once you go home, your dog may be on cage rest for a few days and you will need to keep him under close observation as well.

Has Symptoms

wanting to eat dirt lately.

My Kizzy was an 8 year old lab/border collie mix. She was a brilliant dog who loved to run, went to agility for a few years, lots of training and she was 'my person'. I loved this girl with all my heart. She had the best of the best with me. Home cooked balanced food, a farm to run on with me, she slept on the food of my bed since she was 6 weeks old. We always took her to our vet at any sign of illness and she had her yearly check ups. A few months ago she tore her ACL in her knee, and had special braces made, which she hated and we didn't force. Lately she started going off of her food, not wanting to eat without being coaxed. But would eat. Sometimes she would vomit but not get sick. She started to slow down in her lust for life, I thought it was because of her knee. Then suddenly a few days ago she became gravely ill. Her spleen was huge, so large it was pushing her organs lower in her body. We discovered her heart was small. My vet sent us home with her with prednisone. She became severely anemic literally within a couple of days. Yesterday we had to put her down. It was the hardest thing I've ever had to do and I'm crying now just typing this. I need assurance that this was not poisoning. I can't get that idea out of my head.

Pain medication

My dog was possibly ran over. He is now showing signs of lethargy but little pain. He is still eating and drinking and no blood in the urine. His vet said he could possibly have a damaged spleen but sent him home with some pain medication and informed me to keep an eye on him until we can bring him back in for further testing. My question is, is it likely he can recover without surgery if his spleen has been damaged?

It all depends on the severity of the injury, without examining Jensen I cannot determine the severity of the injury or whether he requires surgery or not; you should think about having further testing done to determine whether there is any injury to the spleen or not. Regards Dr Callum Turner DVM

spladed out

"Our 10 year old standard poodle, Rembrandt, was admitted

to DeLand Animal Hospital on Saturday, 03-31-18, at

approximately 3 p.m. He was diagnosed with a ruptured

spleen and immediate surgery was recommended. We paid

the $1800 expecting the immediate surgery that they had

promised. They lied to us. They promised to save him, but

they did not give him any treatment, tests yes,

treatment no.... DeLand Hospital, their staff, their

technicians and their veterinarians let him suffer SIX

HOURS WITHOUT TREATMENT. After wasting six (6) hours,

they called and requested that we pick Rembrandt up

because they could not find a surgeon Deland Animal

Hospital denied Rembrandt an opportunity to live."

My 11 yr old Springer Spaniel just passed on from an enlarged spleen yesterday. She had an enlarged spleen and tumor on right kidney. Her heart was overworking to compensate. The X-rays showed it was 4X the size of a normal spleen a month ago. She wanted to eat grass a bit and there it up. The past month it grew double the size and she became lethargic, hard to climb stairs and jump onto couch. She started panting when going out to urinate and then this week she started pacing outside and became compulsive to eating dirt despite commands. She vomited up the dirt an hour later and we took her to the vet. He said she only had a few days left as her spleen was so large it was about to rupture. She displayed all the signs listed above by “wag walking”. She was very lethargic, pale, bloodshot eyes, labored breathing and panting. A month ago when this started she had some neurological signs of possible seizure or dementia. He put her on the prescription strength Purina NC and it was very helpful and she loved it. No more brain issues after that. She also bled out her nose for a few days and lots of sneezing. She stopped eating and drinking a day ago.
