Normal dogs and cats should have platelet counts close to or >200,000/µL; normal horses and cows should have platelet counts of 100,000/µL or greater. What is a low platelet count in dogs? Healthy dogs have a platelet count between 175,000-500,000 platelets per microliter of blood, and anything below is diagnosed as low.
How long do dogs live with thrombocytopenia?
Prognosis. A recent study of 45 dogs by Simpson et al (2018), following cases up to 1 year after diagnosis, stated a mortality rate of 11.9%. They reported 89.6% survived to discharge and 31% of those relapsed, within an average of 79 days after successful treatment.
Is thrombocytopenia in dogs curable?
Prognosis for Dogs With Thrombocytopenia Luckily, around 80 percent of dogs diagnosed with ITP will recover. However, relapse is common, so your dog will require lifelong observation and frequent veterinary checkups.
Does thrombocytopenia cause death?
Dangerous internal bleeding can occur when your platelet count falls below 10,000 platelets per microliter. Though rare, severe thrombocytopenia can cause bleeding into the brain, which can be fatal.
What happens if a dog has low platelets?
Platelets bind together to clot broken or leaking blood vessels and prevent unnecessary blood loss, so a low platelet count compromises your dog's ability to control bleeding, which can lead to bruising and excessive bleeding. Thrombocytopenia is the condition of low blood platelets in dogs.
Can dogs live with thrombocytopenia?
Results: A total of 45 dogs were diagnosed, treated and monitored for at least one year for presumed primary immune-mediated thrombocytopenia. 89∙6% of patients survived to discharge and 31% of those experienced a relapse following discharge. The median time from diagnosis to relapse was 79 days.
How do you treat thrombocytopenia in dogs?
The mainstay of treatment for ITP is immunosuppressive corticosteroid therapy, usually given as prednisone starting at 2 mg/kg/day (or 30 mg/m2 for larger-breed dogs). This dose is gradually reduced once the platelet count has returned to normal, typically with dose reductions of 25% every two to four weeks.
Is thrombocytopenia a terminal?
A rare complication of immune thrombocytopenia is bleeding into the brain, which can be fatal. If you're pregnant and your platelet count is very low or you have bleeding, you have a greater risk of heavy bleeding during delivery.
What is the most common cause of low platelet count in dogs?
Decreases in platelets may be caused by anti-platelet antibodies, drugs, toxins, or disorders of the bone marrow. Conditions that consume a large number of platelets (such as massive bleeding or severe clotting disorders) can also deplete platelet numbers.
How low can platelet count go before death?
When the platelet count drops below 20,000, the patient may have spontaneous bleeding that may result in death.
How long does it take for platelets to regenerate in dogs?
When the reduction in platelets and fibrinogen has been carried to an extreme degree the animals display a marked tendency to bleed. The regeneration of platelets after their removal by defibrination is remarkably rapid and amounts, on an average, to about one fifth of the entire number in the blood per day.
How long does it take for steroids to increase platelets in dogs?
Corticosteroids ("steroids") — Steroids prevent bleeding by decreasing the production of antibodies against platelets. If effective, the platelet count will rise within two to four weeks of starting steroids.

What Is Thrombocytopenia in Dogs?
Thrombocytopenia occurs when a dog has a low number of platelets in its blood. Platelets are important for clotting, so if your dog does not have enough of them, it is at risk of sudden bleeding or bruising. It is a fairly common disease in dogs, occurring in as much as 5 percent of dogs admitted to veterinary hospitals. 1
What does it mean when a dog has thrombocytopenia?
Thrombocytopenia occurs when a dog has a low number of platelets in its blood. Platelets are important for clotting, so if your dog does not have enough of them in their body it is at risk of sudden bleeding or bruising. In dogs, it is usually seen as a symptom of an underlying disease and is rarely seen in cats.
What does it mean when a dog has blood in his eye?
Black stool. Blood in urine. Blood in eye. Since thrombocytopenia affects a dog's blood clotting abilities, spontaneous bleeding and hemorrhage can occur. This may happen with or without any trauma. Nose bleeds may also suddenly occur and blood can even be seen in the stool and urine of a dog with thrombocytopenia.
How to treat thrombocytopenia?
The treatment and prognosis for thrombocytopenia will depend on the cause. Medications to treat illnesses and infections, discontinuation of agents causing thrombocytopenia, surgery to remove an enlarged spleen or cancer, controlling of bleeding, and even on rare occasion, platelet transfusions may be necessary for treatment.
What happens if a dog eats poison?
Rodenticide poisoning: If a dog accidentally eats some rodent poison that is designed to cause internal bleeding, thrombocytopenia may be seen alongside hemorrhage.
Can dogs be kept out of reach of ticks?
However, in the case of tickborne diseases, consistent vet recommended tick prevention can be helpful. Dogs with known thrombocytopenia issues should not be used in breeding programmes, rodenticides should always be kept out of reach of pets, and tick-control is recommended.
Can a dog's platelets be destroyed?
Vasculitis: Platelets can be destroyed rapidly in dogs with vasculitis, a disease of the blood vessels, resulting in thrombocytopenia.

Here’s what you should know about the symptoms, causes, and treatments for thrombocytopenia in dogs.
Can dogs bleed with thrombocytopenia?
Although bleeding is a common symptom of thrombocytopenia in dogs, some dogs do not show signs of bleeding, and this largely depends on how low the platelet count is.
How to tell if a dog has thrombocytopenia?
A dog with thrombocytopenia may or may not show signs of bleeding, depending upon how low the platelet numbers are. Common signs of thrombocytopenia include lethargy, loss of appetite, weakness, and pale mucous membranes. Small pinpoint hemorrhages called 'petechiae' may also be found on the mucous membranes such as the inside of the mouth. Larger hemorrhages under the skin, especially on the ventral abdomen and groin area may also be seen. Bleeding from the gums, nosebleeds, black and tarry stools, stools with fresh blood, blood in the urine, hemorrhages in the eye, prolonged bleeding after an injury or surgery, and difficulty breathing may also occur.
How long does it take for a dog to recover from thrombocytopenia?
Most dogs will respond to treatment, especially when diagnosed early and treated aggressively. In cases of immune-mediated thrombocytopenia, immunosuppressive drugs may need to be given for several months or may be required for the life of the dog since some dogs relapse when medications are discontinued.
What is a blood disorder in which platelet numbers are lower than normal which may cause bruising and bleeding?
Summary of Content. Thrombocytopenia is a serious blood disorder in which platelet numbers are lower than normal which may cause bruising and bleeding.
How does thrombocytopenia occur?
Thrombocytopenia can occur because of four processes including decreased production of platelets by the bone marrow, increased use of platelets through blood clotting, destruction of platelets by the immune system, and removal of platelets from the general circulation (se questration).
What is CBC in dogs?
Any dog showing signs of a bleeding problem would have a complete blood count (CBC) and a platelet count performed. A platelet count is a special test done on a blood sample that measures how many platelets are present in a specific quantity of blood. A coagulation profile, which tests for the normal presence of clotting factors in the blood, would also be performed.
How to treat a dog with a high platelet count?
At-home Care. Give all medications as prescribed and limit strenuous exercise, playing, or situations where the dog may become injured until the platelet count has normalized. It is also recommended to feed soft food and do not allow the dog to chew on bones or hard objects that could cause bleeding of the gums.

What is the cause of thrombocytopenia in dogs?
Immune-mediated thrombocytopenia (ITP) is an important cause of severe thrombocytopenia in dogs. In patients with ITP, platelet autoantibodies are made and attach to the surface of platelets, targeting them for destruction by macrophages. This results in profound thrombocytopenia, with platelet counts commonly below the threshold ...

Underlying diseases and clinicopathologic variables of thrombocytopenic dogs with and without platelet-bound antibodies detected by use of a flow cytometric assay: 83 cases (2004-2006). Dircks, Brigitte Hedwig et al. J Am Vet Med Assoc 2009; 235: 960-966.
What breed of dog is most likely to have ITP?
Although ITP can occur in any age or breed of dog, middle-aged female dogs appear to be at greatest risk, and cocker spaniels are the most commonly cited breed predisposition. 4 Patients with ITP may present with unexplained bruising, petechiae (capillary hemorrhages), bleeding, or more vague signs such as lethargy and decreased appetite. In one study, 81% of dogs presented with signs of bleeding, the most common of which was petechiae or ecchymoses (present in 66% of total ITP cases on presentation). Hematemesis, melena, and gingival bleeding were each reported in approximately 20% of cases, while less common signs of bleeding included epistaxis, hematuria, and hyphema. 4 Cavitary bleeding (such as hemoabdomen or hemothorax) is rare in patients with ITP and is more commonly noted in patients with coagulopathy. Fever is common, noted in about one third of patients in one study. 4
How to treat ITP in dogs?
The mainstay of treatment for ITP is immunosuppressive corticosteroid therapy, usually given as prednisone starting at 2 mg/kg/day (or 30 mg/m 2 for larger-breed dogs). This dose is gradually reduced once the platelet count has returned to normal, typically with dose reductions of 25% every two to four weeks. Platelet count should be monitored after each dose reduction to make sure there is no sign of relapse. Adjunctive immunosuppressive medications, including cyclosporine, mycophenolate, and azathioprine, are also frequently used in an attempt to better control the disease or reduce the corticosteroid requirement. However, there is no concrete evidence that use of these medications in addition to steroids provides a significant survival benefit when compared to steroids alone. 7 There is also no consensus on which secondary immunosuppressive drug is best; in one study, there was no difference in outcome in dogs treated with mycophenolate when compared to cyclosporine when each was used in combination with steroids. 8
What does ITP stand for in medical terms?
*NOTE: The abbreviation ITP is from the name for the analogous human condition, idiopathic thrombocytopenic purpura. This is the abbreviation that is used most commonly for the canine form of immune-mediated thrombocytopenia and will be used throughout this article.
What is the risk of bleeding in dogs with ITP?
Dogs with ITP typically have very low platelet counts (<50,000 platelets/uL), which puts them at risk of spontaneous bleeding. Most studies of ITP in dogs report median platelet counts on presentation in the range of 1000-5000 platelets/uL, 1, 4, 5 and another study found that dogs with ITP had lower platelet counts and a higher incidence of anemia than dogs with thrombocytopenia from any other cause. 6 ITP dogs are commonly anemic on presentation and may have other changes on a complete blood count indicative of an inflammatory response, including leukocytosis, increased numbers of band neutrophils, and toxic change. It is important to note that the presence of these changes does not necessarily indicate infection, but rather can be seen simply due to the marked systemic inflammation that occurs with ITP.
What is the best test for ITP?
Recommended diagnostic workup for possible causes of secondary ITP includes testing for tickborne diseases, as well as chest x-rays and abdominal ultrasound to look for evidence of neoplasia. While point-of-care testing such as 4dx is a useful first step in evaluation for tickborne diseases, a broader tick screening can be useful to look for other diseases such as Rocky Mountain spotted fever and Babesiosis. Screening for Babesia infection should be considered particularly in overrepresented breeds, such as greyhounds and pit bull terriers. Due to the high prevalence of tickborne disease in New England, it is also common practice to administer doxycycline as a part of initial therapy for ITP to cover for the majority of tickborne diseases.
Canine immune-mediated thrombocytopenia
Immune-mediated thrombocytopenia (IMT) is a common disease in dogs. Primary IMT is idiopathic, while secondary IMT can result from a variety of infectious agents or some treatments. Symptoms may include lethargy, anorexia and mild pyrexia, together with a low platelet count and associated bleeding disorders.
