Several animal species can harbour, shed and disseminate the bacteria through their urine. Although the circulation of <i>Leptospira</i> among homeless dogs may be common, the presence of <i>Leptospira</i> among household dogs is more important since they can act as important sources of infection for their owners due to the closer contact with humans.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Aim</h3>\u0000 \u0000 <p>The aim of the present study was to detect the presence of <i>Leptospira</i> spp. among household dogs from 15 municipalities of the Caldas department.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Between November 2015 and January 2017, an active household dog sampling was performed in 15 municipalities of Caldas department.
