Immune-Mediated Thrombocytopenia (ITP) in Dogs

High Risk Autoimmune

Immune-Mediated Thrombocytopenia (ITP) is a high-severity autoimmune condition that can affect dogs of all ages and breeds. ITP is a condition where the immune system destroys the dog's own platelets, leading to dangerously low platelet counts and spontaneous bleeding. It can occur as a primary condition or secondary to other diseases, drugs, or infections. It is documented across 4 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 2-8 years. Early signs to watch for include petechiae (pinpoint haemorrhages on skin), bruising, nosebleeds, and blood in urine or faeces. When treatment is required, costs are estimated at £2,000-£5,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.

Signs & Symptoms

The following symptoms are commonly associated with Immune-Mediated Thrombocytopenia (ITP) in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.

  • Petechiae (pinpoint haemorrhages on skin)
  • Bruising
  • Nosebleeds
  • Blood in urine or faeces
  • Prolonged bleeding from minor wounds
  • Lethargy

Treatment Overview

Immunosuppressive therapy with high-dose prednisolone is the mainstay. Vincristine and cyclosporine are added in refractory cases. Transfusions of platelet-rich plasma support severely thrombocytopenic dogs. Treatment is often lifelong.

Typical onset: 2-8 years

Prevention & Screening

While not all cases of Immune-Mediated Thrombocytopenia (ITP) can be prevented, the following steps reduce risk or enable earlier intervention:

  • No proven prevention
  • Avoid triggering drugs where possible

Estimated Treatment Cost

Treatment for Immune-Mediated Thrombocytopenia (ITP) is estimated at £2,000-£5,000, depending on severity, the specific intervention required, and your location. Costs may be higher for surgical procedures or ongoing management. Comprehensive pet insurance covering this condition is strongly recommended.
