Symptoms, when they appear, can include fever, vomiting, abdominal pain, diarrhea, loss of appetite, and kidney failure.
This infection is a zoonotic disease, which means that animals can infect humans.
Leptospirosis is very common in certain areas, but this vaccination may not be necessary for your puppy.
