ABSTRACT
Although there are no comparison studies between breeds in sound localization ability, in a comparison of the hearing thresholds of four dogs representing four breeds (Chihuahua, Dachshund, Poodle, and Saint Bernard) of different sizes, no differences in high-or low-frequency hearing were found. All had maximal sensitivity at "'8000Hz, with a high frequency cut-off "'41,000-47,000 Hz-a far smaller difference than would be predicted by the variation in head size. When compared with other species of comparable sizes, small dogs have a slightly better ability to hear high frequencies, and large dogs have a much better ability to hear high frequencies, than would be expected on the basis of their size (1).
