Leishmaniosis is a serious parasitic disease causing chronic welfare suffering in affected dogs, with treatment managing but rarely curing the condition.
Leishmaniosis causes progressive, multi-system disease with significant welfare impact through skin disease, renal failure, and immune compromise. Treatment significantly improves quality of life but requires lifelong commitment. Prevention through sandfly avoidance, insect repellent collars, and vaccination where available is preferable to managing established disease.
