It's literally just 'Dachs' (German for badger) 'hund' (German for dog). Surely 'Hund' is such common knowledge it's really only the 'Dachs' one has to remember? This week alone I've seen it spelt 'Dashchund, Dashound, Daxan and Dachssund. I realise there are some breeds out there with tricky spelling that are maybe hard to get your head around, but Dachshund, I really don't get the confusion over!
