In the past 30 days, confirmed cases of leptospirosis have been reported in five different counties across Massachusetts. This serious bacterial disease can affect both dogs and humans, and is often spread through the urine of infected wildlife, especially in areas with standing water.
Counties with recent cases include:

What you need to know:
Leptospirosis is transmitted through contaminated water, soil, or direct contact with infected animals.
Symptoms in dogs include fever, vomiting, lethargy, muscle tenderness, and increased thirst or urination. In severe cases, it can lead to kidney or liver failure.
Dogs that spend time outdoors, near water sources, or around wildlife are at higher risk.
It is zoonotic, meaning it can spread from animals to humans.
✅ Prevention tips:
Avoid letting your dog drink from or swim in stagnant water
Reduce exposure to areas with rodent or wildlife activity
