Abstract:
Male beagle dogs were subjected to various hot air temperaturehumidity combinations in an attempt to develop a safe temperaturehumidity index for dogs being transported by aircraft. Only those environments in which all exposed dogs could maintain a rectal temperature less than 108 F during 6 hours of continuous exposure were considered safe. Results from the experiments provided data to formulate an equation used in defining the tolerance index. Increasing the environments humidity serves as a catalyst in decreasing a dogs tolerance to heat. In order to offset the effects of an increase in air temperature starting at 85 F with a 90 percent relative humidity, relative humidity would need to be decreased by 4 percent for every 1 F rise in temperature. Changes in rectal temperature and behavior barking and excessive movement in relation to the exposure environment are presented and discussed.
