As canine leishmaniosis spreads northward with climate change, prevention through vaccination, parasite control, and owner education is becoming increasingly important across a wider geographic area.
Canine leishmaniosis causes progressive chronic disease affecting skin, kidneys, and immune function. Prevention is far preferable to treating established infection, which requires lifelong management. As the endemic zone expands, more dogs require protection through vaccination and repellents. Educating owners about risk and prevention before travel to endemic areas significantly reduces individual dog welfare suffering.
