Dog Immune-Mediated Haemolytic Anaemia

Immune-mediated haemolytic anaemia (IMHA) is a life-threatening condition where the immune system destroys red blood cells, requiring aggressive treatment and careful monitoring.

Key Facts

IMHA is one of the most common immune-mediated diseases in dogs
The immune system produces antibodies against the dog's own red blood cells
Affected dogs may become severely anaemic requiring blood transfusions
Immunosuppressive treatment with steroids and additional drugs is the cornerstone of therapy
Relapse occurs in up to 50% of cases, requiring long-term monitoring

Welfare Considerations

IMHA causes profound weakness, breathlessness, jaundice, and collapse in severe cases. The condition can deteriorate rapidly and is life-threatening without intervention. Treatment involves significant side effects from high-dose immunosuppression. Dogs require intensive nursing care and monitoring. Owners need realistic discussions about prognosis and quality of life throughout treatment.

What You Can Do

Seek emergency veterinary care immediately if your dog shows sudden weakness, pale gums, or collapse
Follow immunosuppressive treatment protocols exactly as prescribed
Monitor packed cell volume regularly to detect relapse early
Discuss with your vet the balance between side effects and disease control
Support research into improved diagnostic and treatment protocols for IMHA
