From September 2001 to September 2002 3,417 blood samples from dogs were submitted to the microscopic agglutination test (MAT), and we found 13.11% of seropositivity, being the most reactive serovars canicola, ballum pyrogenes and icterohaemorrhagiae. Higher prevalence was found in Center southern with 22,48%, 19,12% in Eastern and 13,20 in Northeastern neughborhoods. Pampulha region, with 8,17%, presented the smallest percentage of positive reactions. The variables sex, race, age and type of apprehension reveal an increased prevalence of infection in male wandering dogs of undefined race, without difference to age. Months with highest number of dog infection were December 2001 and January 2002, corresponding to the perod of downfall and increased temperature.
