In the United States, canine leishmaniasis is a relatively rare disease. Because it's uncommon and symptoms vary widely, a veterinarian might not immediately recognize leishmaniasis in a dog. Generally, leishmaniasis symptoms appear between two and four months after disease transmission. Asymptomatic dogs can carry the parasite causing leishmaniasis for years. Let your vet know if your dog has been in a part of the world where leishmaniasis is prevalent.

Leishmaniasis Symptoms
-
Dogs with leishmaniasis might develop skin lesions, hair loss, eye problems -- including blindness -- and ear ulceration. Some affected dogs lose weight and lack energy. Other symptoms include vomiting and diarrhea, anemia, excessive drinking and urination, lameness, odd nail growth and nasal discharge. In severe cases, infected dogs might experience heart disease or organ failure. However, some type of dermatological issue is the primary symptom for the overwhelming majority of dogs. Even with treatment, symptoms might only improve temporarily.
