IMHA: Autoimmune Haemolytic Anaemia Welfare in Dogs

Key Welfare Facts

IMHA causes destruction of red blood cells by the immune system, leading to severe anaemia and life-threatening crisis.
Affected dogs show rapid breathing, pale gums, lethargy, and collapse, representing an acute welfare emergency.
Some dogs require blood transfusions to stabilise them before immunosuppressive treatment takes effect.
Treatment with prednisolone and additional immunosuppressants achieves remission in most dogs over weeks.
Thromboembolism is a dangerous complication requiring additional prophylactic treatment in high-risk dogs.
Relapses occur in 15-30% of cases, requiring long-term monitoring and willingness to restart treatment promptly.

Welfare Assessment

IMHA is a serious life-threatening welfare emergency that responds well to aggressive immunosuppressive management when started promptly. Long-term welfare requires commitment to monitoring for relapse and rapid response to early signs of recurrence.

What You Can Do

Seek emergency veterinary care immediately for any dog showing pale gums with rapid breathing
Commit to the full immunosuppressive treatment course and careful tapering to prevent relapse
Monitor for thromboembolism signs and discuss prophylactic anticoagulation with your vet
Schedule regular follow-up haematology checks to detect early relapse before crisis develops
