Leptospirosis is a bacterial disease transmitted through contaminated water and wildlife urine. It causes severe kidney and liver failure in dogs and is preventable through vaccination and environmental management.
Leptospirosis causes acute and severe suffering in affected dogs through kidney failure, liver damage, bleeding disorders, and overwhelming systemic infection. The disease can progress from initial vague signs to life-threatening organ failure within days, causing profound distress for the animal and anguish for owners. Treatment requires intensive veterinary care including fluid therapy, antibiotics, and organ support, which is expensive and not always successful. Vaccination is highly effective, inexpensive, and represents one of the clearest welfare and public health wins available to dog owners. Awareness of environmental risk factors allows owners to take additional precautions such as preventing dogs from drinking from stagnant water sources.
