The author discusses findings from a survey completed by 19 dog handlers who worked in Haiti after the 2010 earthquake. Overall, the author found that dogs encountered 12.6 adverse effects for every 1,000 hours worked. Handlers reported that all health issues were cured either during the deployment or within two weeks after demobilization.
