Factors Influencing Odor Sensitivity in the Dog
Abstract
Detection curves were previously derived for alpha-ionone for four German Sheperd dogs. To determine the generality of those findings, six men and one woman were tested in the same apparatus using comparable procedures and the same compound. Human detection curves reach their asymptotes in one and half units of concentration while those of dogs extend over five log units. The marked discontinuity in the slope of the canine detection curves was also seen in the curves for four of the human subjects and in one case extends over 50 percent of the dynamic range. Three subjects showed no discontinuity. A technique has been developed for the quantitative analysis of the relation between odor detection task and sniff parameters. Sniff flow rate, frequency and amplitude are recorded from the output of a pheumotachometer behind one port.
