Canine ehrlichiosis is a disease that affects dogs. The brown dog tick and lone star tick have been implicated in transmission.


Infected dogs can go for years without experiencing any major symptoms or demonstrating only occasional mild anemia and loss of appetite. As the disease progresses, symptoms may include fever, discharge from the eyes and nose, loss of appetite, depression, weight loss, anemia, overall decline in body condition, reduced blood platelet count, respiratory problems, lameness, and neurological disorders. These symptoms may become chronic in later stages of the disease.


Infected dogs generally respond positively to a course of antibiotics. Prolonged recovery periods have been noted in dogs with chronic ehrlichiosis and severe bone marrow damage. You should consult your veterinarian for proper treatment of your dog.
