Overview
- Veterinary groups highlight that dogs can contract Leptospira from urine-contaminated water in puddles, drains, streams and canals.
- PDSA lists vomiting, diarrhoea, coughing, jaundice, breathing difficulty and lethargy as key canine symptoms requiring urgent veterinary care.
- Experts warn some dogs may show few or no signs yet shed bacteria, and severe cases can prove fatal within about two days of symptom onset.
- Human infections remain uncommon in the UK, with higher risk for people working with animals or water and for those taking part in wild swimming and water sports.
- Guidance notes treatment typically involves antibiotics, dog vaccination can reduce severity and shedding, and prevention includes handwashing, covering cuts, protective clothing, rodent control and avoiding likely contaminated waters.
