Here are some factors that can influence a Dachshund's lifespan:
* Genetics: Some Dachshunds are genetically predisposed to certain health issues that can shorten their lifespan.
* Diet: A healthy diet is essential for a long and healthy life.
* Exercise: Regular exercise helps to keep Dachshunds healthy and fit.
* Veterinary care: Regular checkups and preventative care can help to catch and treat health problems early.
* Environment: A safe and stimulating environment can help to reduce stress and promote longevity.
It's important to note that these are just general guidelines, and individual Dachshunds may live longer or shorter than the average lifespan.
