Dog Immune-Mediated Haemolytic Anaemia Welfare

Immune-mediated haemolytic anaemia is a serious welfare emergency that causes acute and potentially fatal anaemia requiring intensive treatment.

Key Facts

IMHA occurs when the immune system attacks red blood cells causing severe anaemia
Affected dogs show pale gums, extreme lethargy, rapid breathing and jaundice
Blood transfusion may be required as a life-saving bridge to immunosuppression treatment
Immunosuppressive therapy including steroids and often additional agents is required for weeks to months
Relapses can occur requiring long-term monitoring and readiness for repeat treatment

Welfare Considerations

IMHA causes acute severe welfare compromise from profound anaemia, and treatment involves intensive immunosuppression with side effects. Dogs surviving the acute crisis can recover well, but the welfare burden of treatment is significant and owner support is important.

What You Can Do

Seek emergency veterinary care immediately for dogs with pale gums or extreme sudden lethargy
Work with an internal medicine specialist for optimal management of IMHA cases
Prepare for long-term monitoring and possible relapse management after initial treatment
