Leptospirosis is a bacterial infection that can have serious consequences in dogs and can also affect humans. The bacteria, known as Leptospira, primarily affects the liver or kidneys of dogs and other mammals1.
This disease is most often transmitted to dogs through mucous-membrane (mouth, nose, or eye) contact with the urine of infected animals and/or contaminated food or water2. Dogs usually become infected by drinking, swimming, or walking through contaminated water3.
Common clinical signs reported in dogs include fever, vomiting, abdominal pain, diarrhea, refusal to eat, and severe weakness14. Some dogs may show signs of lethargy, anorexia, vomiting, abdominal pain, and changes in urination5.
Leptospirosis is responsive to antibiotics and complete recovery is possible. However, some dogs that survive may be left with chronic kidney or liver disease. Some dogs may not survive if the infection has caused significant organ damage or severely affected the ability of blood to form clots3. With correct and aggressive treatment, your dog with leptospirosis has an 80% survival rate, but their kidney or liver function may be permanently impaired3.
Leptospirosis is a disease that can affect humans and animals, including pets6. In humans, symptoms range from flu-like symptoms to kidney failure and even death3.
Prevalence varies by region, with certain areas having higher rates of infection. For example, leptospirosis has been found in all five boroughs of New York City (NYC). The Health Department investigates about two human and 15 dog cases each year7.
Prevention is key when it comes to leptospirosis. Regular vaccination, avoiding areas where the bacteria may be present, and good sanitation practices can help reduce the risk of infection28.
There have been many localized outbreaks in the last couple of years so vaccinating your French Brittany against Lepto is becoming more important than ever
