A 5-year-old male Labrador Retriever that lived outdoors was presented to the animal hospital with a right hind limb lameness. The lameness had been present for more than 10 days, and there was a severe swelling of the right stifle joint. The dog underwent physical, laboratory, and radiographic examinations. As a result, the dog was diagnosed with infectious monoarthropathy secondary to granulocytic ehrlichiosis. The dog received medication for the rickettsial arthritis and surgical treatment for reconstruction of the soft tissue damage caused by the infection. After treatment, the function of the dog's leg was recovered. This report describes a case of atypical monoarthropathy caused by ehrlichiosis in a dog.
