Why a cross, why not just either a smooth-haired or a wire haired miniature dachshund? Beware any "breeder" purposely selling such dogs! If you would like a cross breed Guest, why not take a trip to your local rescue, there will be plenty in there to choose from? Otherwise, get in touch with the breed club of either breed to ask about recommended breeders-those breeding pedigrees!
Hope that helps :)
