What is Leptospirosis
Leptospirosis is a disease caused by a bacteria called Leptospira. Dogs most commonly catch leptospirosis from infected urine, for example, from water (in particular, slow-moving or stagnant water) or soil that has been contaminated with infected urine from another animal (mainly rats). Leptospirosis can spread to other pets and humans.
