What breed of dog says af? - in detail

The breed of dog that commonly produces the sound "af" is the Basenji. This unique trait sets the Basenji apart from other breeds and has earned it the nickname "barkless dog." Unlike most dogs, which produce the characteristic "woof" or "bark," the Basenji's vocal repertoire includes a distinctive yodel-like sound that can be described as an "af." This peculiarity is due to the shape of their larynx, which differs from that of other dog breeds. The Basenji's vocal cords are shorter and thicker, making it physically impossible for them to produce traditional barking sounds. Instead, they communicate using a range of vocalizations, including groans, yodels, and the characteristic "af" sound. This unique ability has become one of the most recognizable traits of the Basenji breed, contributing to its distinct personality and charm.
