* Dachshund: 12-15 years
* Terriers: This varies widely depending on the specific breed. Some terriers, like the Jack Russell, have a lifespan of 13-16 years, while others, like the Airedale Terrier, have a lifespan of 10-13 years.
Therefore, a Dachshund Terrier mix's lifespan is likely to be somewhere between 10 and 16 years, depending on the specific terrier breed involved.
Other factors that can influence lifespan:
* Genetics: The individual dog's genetics play a significant role in its lifespan.
* Health: Good health care, including regular vet checkups, vaccinations, and parasite prevention, can help extend a dog's life.
* Lifestyle: A healthy diet, plenty of exercise, and a loving home environment can all contribute to a longer lifespan.
To get a more accurate estimate of your Dachshund Terrier mix's lifespan, talk to your veterinarian. They can assess your dog's individual health and provide a more personalized estimate.
