A single bacterial species was cultured from 44\/99 dogs (44%) and multiple bacterial species were isolated from 55\/99 dogs (56%). Suppurative inflammation with intracellular bacteria was identified cytologically in 78 of 105 dogs (74%). In 27 dogs that lacked cytologic evidence of sepsis, mixed (n = 18) and neutrophilic (n = 9) inflammation was reported, and Mycoplasma spp. (13\/27) or Bordetella spp. (7\/27) were most commonly isolated.
