Have you heard of leptospirosis? It’s a dangerous infectious disease, particularly for dogs, transmitted by ingesting water contaminated with infected urine.
The most frequently infected wild animals are raccoons, skunks and rodents. Some dogs are asymptomatic carriers and can contaminate their environment, while others can become seriously ill and die.
Leptospirosis can also be transmitted to humans through direct or indirect contact with infected animal urine. Fortunately, a vaccine protecting against 4 strains of leptospirosis is available for dogs, and must be administered annually.
Leptospirosis is rare in cats.
Dogs at risk are those that :
- Live near water;
- Are in contact with farm animals;
- Bathe or drink water from lakes and rivers;
- Have access to stagnant water.
Symptoms appear within 4 to 12 days of exposure and may include fever, vomiting, loss of appetite, conjunctivitis and muscle pain.
Shortly after the onset of these clinical signs, some dogs develop renal failure, and occasionally liver failure. Signs include decreased urine production, jaundice, dark yellow urine and difficulty breathing.
By remaining vigilant and taking the necessary preventive measures, such as annual vaccination, you can protect your dog against the risks of leptospirosis. Although rare in cats, leptospirosis can be fatal in dogs and a danger to humans. Consult your veterinarian to assess the risks specific to your pet and ensure its safety.
