This study was attempted to survey on the prevalence of canine heartworm(Dirofilaria immitis) infection among 100 dogs(male 39, female 61) on the nine breeding farms in eastern Chungnam province in December 2002. Blood samples taken from dogs were examined for the presence of D immitis microfilaria by the modified Knott’s test and an antigen test was using FASTest/ HW Antigne kit (Mega Cor A-6912 Horbranz-Austraia). 1. Eleven(11.0%) of the 100 examined dogs were microfilaria positive, while nineteen dogs(19.0%) were antigen positive, which suggested that the antigen test was more sensitive than the microfilarial test in detecting heartworm infection. 2. Infected dogs were observed higher more at 2 years older ages(4/48, 8.3%) and male(9/39, 23.1%) than young ages(4/48, 8.3%) and female(10/61, 16.4%). 3. The regional infection rates were of Gongju(15/43, 34.9%), Geumsan(4.27, 14.8%), while none of infection dogs in Yeongi(0/30, 0%). 4. Survey for hematological values of D immitis infected dogs : WBC and eosinophils were 21.47.2 k/, 3.50.4 k/, respectively. In conculsion, this study could be overemphasized the importance of control program the heartworm in eastern Chungnam province
