Just like any other dog breed, Dachshunds are more prone to certain health issues and less prone to others. Some things are less preventable due to genetics, while others can be prevented (or at least reduced) with proper diet and lifestyle.
Educating yourself about how to recognise these health issues early can greatly improve your Dachshund’s prognosis and quality of life. And, even more importantly, being more aware will also equip you with the knowledge you need to help prevent these health issues or at least keep symptoms to a minimum.
IVDD is a disease and not an injury. The trauma to the spinal cord results from hardening of the discs due to the disease.
