Ticks were collected, and taxonomic identification was carried out. Prevalence rate and percentage of frequency of positive dogs (FP) per month were calculated. Results obtained detected a wide distribution of R. sanguineus in the dogs' population studied. Prevalence from March to June was higher than 40%, and the maximum one was recorded in April(60%). A higher FP was a 3.86% observed in July followed by 2.67% observed in April and November 1992. The lowest FP was found in December 1991, and February and September 1992. Tick specimen were collected along the study period and 2.5 generations per year were calculated.
