Dachshund » Dashound
It’s easy to see the source of the reanalysis… everyone knows that ‘hound’ is nearly synonymous with ‘dog’… and the eggcorners can’t really be blamed since (I think) ‘hund’ means dog (in German?)
(I also discovered from some pet owners’ forum that other misspellings/shortenings are ‘dotsen’ and ‘doxen’. I can’t see the logic behind the first, since they’re not usually spotted, but perhaps the second has something to do with the sound of ‘dogs’? Or perhaps those two are just short-forms, rather than genuine mistakes. But ‘dashound’ certainly seems to be a widespread, eggcorny error. ‘Dashhound’ is less common, but it exists…)
