As a breed, the dachshund typically has a long lifespan, averaging from 12 to 15 years or more. The breed is, unfortunately, predisposed to several diseases. As a dachshund owner, you should be aware of these diseases and their symptoms and informed about when they are likely to develop. Always be sure to have your veterinarian examine any suspicious physical or behavioral symptoms your dachsie might be having. The best hedge against disease is vigilance and immediate veterinary care.
