Bay Area veterinarians and public health officials are warning of a spike in leptospirosis, a highly contagious bacterial disease that can be deadly in dogs and, in rare cases, spread to humans. Cases are rising across the region and in Los Angeles County, particularly during the rainy season when bacteria thrive in standing water. Dogs can contract leptospirosis through contact with contaminated water, soil, mud, or urine—often from rats. Symptoms include increased thirst and urination, loss of appetite, lethargy, vomiting, and reluctance to move, while humans typically experience flu-like symptoms.
The report highlights the case of Bubba, a nine-year-old dog who survived initial treatment after a rapid diagnosis but later died due to underlying chronic liver disease worsened by infection. Veterinarians stress that early diagnosis, isolation, and antibiotics are critical to prevent severe kidney and liver damage and limit spread. Annual vaccination and prompt Veterinary care remain the best protection for pets and owners.
