Although some wirehaired Dachshunds may have a slight doggy odor, all dogs are not hypoallergenic. Smooth Dachshunds can also have a scent, though it is less noticeable than that of the wirehaired variety. However, because there is no clear cut answer to this question, it is best to consult with a veterinarian or dog groomer before bringing a wirehaired Dachshund home.
