Objective—To compare measurements of body temperature
obtained with auricular thermometers versus
rectal thermometers in dogs with otitis externa.
Animals—100 client-owned dogs: 50 with and 50
without clinical evidence of otitis externa.
Procedure—Dogs were evaluated for the presence
of otitis externa on the basis of clinical signs, otoscopic
examination, and cytologic evaluation of ear
exudate. Auricular and rectal temperatures were
obtained simultaneously in all dogs prior to and following
Results—There was a high correlation between
auricular and rectal temperatures in dogs with otitis
externa both prior to and after ear manipulation.
Significant differences were not detected in temperature
measurements among dogs with different
degrees of otitis externa.
Conclusions and Clinical Relevance—Auricular
temperature readings obtained by use of an auricular
thermometer in dogs with otitis externa are accurate
measurements of body temperature, compared with
rectal temperature measurements. Temperature
measurements are reliable before and after examination
of the ear canal. (J Am Vet Med Assoc 2002;
