The aim of this study was to investigate the occurrence of canine leptospirosis using collected samples from four neighborhoods in the city of Cruz das Almas - Bahia, evaluating clinical and serological aspects. The diagnosis of leptospirosis was obtained by the Microscopic agglutination test technique, using 19 serovars. The frequency of seropositive animals found was 30% (60/200), being the Javanica sorovar the most commonly found, occurring in 15.4% (6/39) of the positive samples. Statistically, clinical signs correlated to the positive animals were the heart rate (p = 0.002; OR = 9.68), jaundice (p = 0.032; OR = 4.68), haematuria (P = 0.004; OR = 12, 32) and apathy (p = 0.046; OR = 4.95). It is concluded that seropositive animals for leptospirosis may present different clinical signs, and the heart rate was the most significant factor in this experiment.
