Leptospirosis is a parasite that is shed in the urine of infected animals and can be passed by bite wounds, ingestion of infected tissue, or contact with contaminated soil, food, water, or bedding. If the parasite is ingested by a dog, severe and life-threatening disease can develop.
We recommend an initial vaccine series (2 injections given 3-4 weeks apart) and then an annual booster, or as recommended by your veterinarian.
