   The ability of genetically similar rickettsial organisms, such as R parkeri, to cause clinically similar disease in dogs is unknown. Because of their susceptibility to R rickettsii and relatively higher rates of tick exposure, dogs may serve as excellent sentinels of risk for R rickettsii infection in people.
