Canine immune-mediated thrombocytopenia causes severe platelet depletion with bleeding risk, requiring immunosuppression and careful welfare monitoring during treatment.
IMT causes acute suffering through spontaneous hemorrhage and the anxiety of potential life-threatening bleeds. Dogs with very low platelet counts require strict rest restrictions - excitement or trauma can trigger catastrophic internal bleeding. The immunosuppressive treatment required has its own welfare impacts including increased infection susceptibility, GI side effects, and behavioral changes. Careful monitoring during treatment, prompt response to bleeding episodes, and systematic reduction of immunosuppression as platelet counts recover optimizes welfare through the recovery period.
