A standard Dachshund should weigh between 16-32 pounds, while a miniature Dachshund should weigh between 11-16 pounds. It is important to regularly monitor your Dachshund's weight and consult a veterinarian if you notice any sudden changes. Maintaining a healthy weight can improve their overall health and prevent potential health issues.
