Dog Leptospirosis Vaccination Welfare

Leptospirosis is a serious bacterial disease transmitted through rat urine that causes severe liver and kidney disease in dogs, with vaccination providing effective protection.

Key Facts

Leptospirosis causes liver and kidney failure with high mortality in unvaccinated dogs
The bacteria survive in water and moist soil contaminated by rodent urine
Working dogs, dogs near water, and dogs in areas with rat populations have highest risk
Annual vaccination is required as immunity wanes rapidly compared to core vaccines
Antibiotic treatment is available but most effective when started early

Welfare Considerations

Leptospirosis causes severe organ failure causing intense suffering and death in affected dogs. Annual vaccination provides effective welfare protection for at-risk dogs, making leptospirosis vaccination a welfare priority especially for dogs with outdoor access.

What You Can Do

Vaccinate your dog against leptospirosis annually especially if they access waterways
Avoid allowing dogs to drink from puddles or stagnant water in endemic areas
Seek prompt veterinary care if your dog develops jaundice or signs of kidney disease
