Companion Dog Leptospirosis Prevention Welfare

Leptospirosis is a potentially fatal bacterial infection in dogs requiring vaccination and risk awareness for welfare protection.

Key Facts

Leptospirosis is transmitted through contact with infected urine often via water and muddy environments
New serovars have emerged in UK requiring updated vaccine formulations covering broader strains
Liver and kidney failure are primary causes of death in untreated leptospirosis
Dogs with access to standing water or rat habitats are at highest risk

Welfare Considerations

Leptospirosis causes severe acute illness with liver and kidney failure causing intense suffering and high mortality without prompt treatment. Prevention through annual vaccination with current broad-spectrum vaccines is essential for at-risk dogs. Early diagnosis and antibiotic treatment improve welfare outcomes.

What You Can Do

Vaccinate dogs annually with a current broad-spectrum leptospirosis vaccine
Avoid allowing dogs to drink from or swim in stagnant water in rat habitat areas
Seek urgent veterinary assessment for dogs showing fever, vomiting, or jaundice
