Smooth-Haired Dachshunds need very little grooming thanks to their short, smooth coat. Apart from a regular rub down with a damp cloth, the occasional shampoo is all the grooming your Smooth-Haired Dachshund is likely to need.
Long-Haired Dachshunds ideally need a daily brush with a bristle brush and/or comb.
Wire-Haired Dachshunds ideally need a daily brush with a bristle brush and a twice-yearly visit to the dog groomer to have their coats hand stripped.
