Dachshunds are actually quite healthy and long-lived dogs if they are not prone to herniated discs (dachshund paralysis) and heart valve insufficiency (especially wire-haired dachshunds). They are good to feed converters with mostly healthy appetites. Even more so than with most other dog breeds, being overweight in the dachshund means a reduction in the quality of life and also a threat to their health. For the sake of your dog, pay close attention to its slimline!
