Leptospirosis is an infectious disease caused by the Leptospira bacteria, which can seriously injure the liver and kidney. Leptospirosis is a zoonotic disease(can spread from animals to humans), which are found in soil and water. The most common reservoirs of the disease are wild animals such as rodents.
Dogs can be infected by contact of their abraded skin and wounds with infected water and soil, through a bite from other animals, and by eating infected source.
Signs of Leptospirosis in dogs vary. Clinical signs usually show in the first week after infection. Some can show mild to no symptoms, while others may experience severe illnesses and even death.
Common symptoms are fever, vomiting, diarrhea, lethargy, Jaundice(yellowing of the skin), dehydration, or inflammation in the eyes. If not treated, the disease can lead to kidney and liver failure and severe lung disease.
Treatments for Leptospirosis are antibiotics and supportive care.
