From WikiGTA - The Complete Grand Theft Auto Walkthrough
The Dashound is a coach in Grand Theft Auto V.
Dashound is a common misspelling of dachshund.
- The Dashound initially displayed Dashhound (with double h) when entered; one of the patches has changed this. Unpatched versions of Grand Theft Auto V will naturally still show the misspelled name. The Rockstar Games Social Club page still shows, and is named conform the old spelling, see: http://socialclub.rockstargames.com/games/gtav/career/vehicles/michael/service/dashhound
