The raccoon dog (Nyctereutes procyonoides) may be infected by Dirofilaria immitis. However, there has been no report on dirofilarial infection in the raccoon dog in Korea. In this study, we report on D. immitis infection in two wild raccoon dogs captured in the Daejeon area. The two raccoon dogs were referred to the Veterinary Teaching Hospital, Chungnam National University for diagnosis of D. immitis infection. The modified Knott's test for the detection of blood D. immitis microfilariae was positive, and serological test (FASTest$^{(R)}$ HW Antigen ELISA kit, Diagnostik Mega Cor, Austria) for D. immitis was positive as well. Additionally, D. immitis microfilariae were differentiated from other microfilariae by using acid phrnphatase histochemical staining (Leucognost-SP$^{(R)}$kit, Diagncstica MERCK, Germany). The two raccoon dogs were necropsed and D. immitis infection was confirmed.
