They may be smooth-haired, wire-haired, or long-haired. The name dachshund is of German origin and literally means 'badger dog,' from Dachs ('European badger') and Hund ('hound, dog'). The pronunciation varies in English: variations of the first and second syllables include /ˈdɑːks-/, /ˈdæks-/ and /-hʊnt/, /-hʊnd/, /-ənd/. It may be mispronounced as /ˈdæʃ-/hound by some English speakers. The German word is pronounced . Light-colored dachshunds can sport amber, light brown, or green eyes; however, kennel club standards state that the darker the eye color, the better. Dapple and double dapple dachshunds can have multi-coloured “wall” eyes with fully blue, partially blue or patched irises due to the effect of the dapple gene on eye pigmentation expression.
