Dept reports, Dunbar Dogs being dogs growl, bite, i.e.natural behavior Others?

13 MCAS Potentially Dangerous Dog Program 25 years later (March 2012) Research Question: Is our Potentially Dangerous Dog program reducing recidivism 25 years after initial program evaluation in 1991? Methodology 1. Identified all dogs classified as a Potentially Dangerous Dog for the first time for each of three years: FY2006, FY2007, FY Established three Cohort groups of classified dogs (2006, 2007, 2008) 3. For each cohort group, identified all dogs that had a subsequent qualifying event within one, two, and three years of initial classification 4. A subsequent qualifying event is defined as a recidivism event. 26 Dogs Recidivism within 1 yr Recidivism w/in 2 yr Recidivism w/in 3 yr Level Classified Percent No. Percent No. Percent No. Percent Level % % % % Level % % % % Level % % % % TOTAL % % % % Preliminary Data Three years of data 2006, 2007, 2008 Recidivism 2006 = 25.9% 2007 = 21.2% 2008 = 20.7% Total = 23.0% 27 13
