RESUMEN
The seropositivity of dogs to Borrelia burgdorferi, Anaplasma phagocytophilum, and Ehrlichia canis antibodies, and Dirofilaria immitis antigen was assessed in Canada. Borrelia burgdorferi had the highest seroprevalence, while that of Dirofilaria immitis has not changed significantly in the past 20 y. The risk for these vector-borne infectious agents in Canadian dogs is low but widespread with foci of higher prevalence.

A 1.5-year-old dog was evaluated for abnormal mentation, collapse, and weight loss. Radiographs and ultrasonographs revealed soft tissue masses in the mid abdomen. Ultrasound-guided fine-needle aspirates provided a diagnosis of malignant epithelial or round cell neoplasia. Histopathologic and immunohistochemical findings on the tumors were consistent with a primitive neuroblastoma.
