Dog Leptospirosis Prevention Welfare

Leptospirosis is a serious bacterial infection in dogs that causes severe systemic disease and kidney failure, with welfare and public health implications.

Key Facts

Leptospirosis is transmitted through water and soil contaminated with infected animal urine
Unvaccinated dogs in urban areas are increasingly affected as rat populations grow
The disease causes acute kidney and liver failure with mortality rates up to 30%
Vaccines are available for the most common serovars but immunity wanes annually
Dogs that survive may have permanent kidney damage affecting long-term quality of life

Welfare Considerations

Leptospirosis causes acute pain, systemic organ failure, and death in affected dogs. Prevention through annual vaccination and hygiene measures avoids preventable suffering. The disease is also a zoonosis, making prevention important for public health.

What You Can Do

Vaccinate your dog annually against leptospirosis, especially if they swim or live in cities
Avoid letting dogs drink from puddles or stagnant water
Seek immediate veterinary care if your dog shows lethargy, vomiting, or jaundice
